DETAILED DESCRIPTION As used herein, herbicide and herbicidal active ingredient mean a compound that controls undesirable vegetation when applied in an appropriate amount.
As used herein, control of or controlling undesirable vegetation means killing or preventing the vegetation, or causing some other adversely modifying effect to the vegetation e.g., deviations from natural growth or development, regulation, desiccation, retardation, and the like. 1002485149 As used herein, a herbicidally effective or vegetation controlling amount is an amount of herbicidal active ingredient the application of which controls the relevant undesirable vegetation.
As used herein, applying a herbicide or herbicidal composition means delivering it directly to the targeted vegetation or to the locus thereof or to the area where control of undesired vegetation is desired. Methods of application include, but are not limited to, pre- emergently contacting soil or water, or post-emergently contacting the undesirable vegetation or area adjacent to the undesirable vegetation.
As used herein, plants and vegetation include, but are not limited to, dormant seeds, germinant seeds, emerging seedlings, plants emerging from vegetative propagules, immature vegetation, and established vegetation.
As used herein, agriculturally acceptable salts and esters refer to salts and esters that exhibit herbicidal activity, or that are or can be converted in plants, water, or soil to the referenced herbicide. Exemplary agriculturally acceptable esters are those that are or can be hydrolyzed, oxidized, metabolized, or otherwise converted, e.g., in plants, water, or soil, to the corresponding carboxylic acid which, depending on the pH, may be in the dissociated or undissociated form.
Suitable salts include those derived from alkali or alkaline earth metals and those derived from ammonia and amines. Preferred cations include sodium, potassium, magnesium, and aminium cations of the formula: 13 14 15 16 R R R R N 13 14 15 16 wherein R , R , R and R each, independently represents hydrogen or C -C alkyl, 1 12 C -C alkenyl, or C -C alkynyl, each of which is optionally substituted by one or more 3 12 3 12 substituents such as hydroxy, C -C alkoxy, C -C alkylthio, or phenyl groups, provided that 1 4 1 4 13 14 15 16 13 14 15 16 R , R , R and R are sterically compatible. Additionally, any two R , R , R and R together may represent an aliphatic difunctional moiety containing one to twelve carbon atoms and up to two oxygen or sulfur atoms. Salts of the compounds of Formula (I) can be prepared by treatment of compounds of Formula (I) with a metal hydroxide, such as sodium hydroxide, with an amine, such as ammonia, trimethylamine, diethanolamine, 2-methyl- thiopropylamine, bisallylamine, 2-butoxyethylamine, morpholine, cyclododecylamine, or benzylamine, or with a tetraalkylammonium hydroxide, such as tetramethylammonium hydroxide or choline hydroxide. Amine salts of compounds of Formula (I) are useful forms 1002485149 or derivatives of compounds of Formula (I) because they are water-soluble and lend them- selves to the preparation of desirable aqueous based herbicidal compositions.
Other forms or derivatives of compounds of the Formula (I) include N-oxides of compounds of Formula (I). Pyridine N-oxides can be obtained by oxidation of the corresponding pyridines. Suitable oxidation methods are described, for example, in Houben-Weyl, Methoden der organischen Chemie [Methods in organic chemistry], expanded and subsequent volumes to the 4th edition, volume E 7b, p. 565 f.

EXAMPLES SYNTHESIS OF PRECURSORS General Considerations: Fluorine spectra were acquired at 376 MHz on a Bruker DRX400 spectrometer. The spectra were referenced to trichlorofluoromethane (CFCl ) as an external standard and were typically conducted with proton decoupling.
Example 1: Preparation of methyl 4-amino-3,6-dichloropicolinate (Head A) Prepared as described in Fields et al., WO 2001051468 A1.
Example 2: Preparation of methyl 4-amino-3,6-dichlorofluoropicolinate (Head B) N CH Prepared as described in Fields et al., Tetrahedron Letters 2010, 51, 79-81. 1002485149 Example 3: Preparation of 2,6-dichloromethoxyvinyl pyrimidine Cl CH Cl CH Cl N Cl N To a solution of commercially available 2,6-dichloromethoxy pyrimidine (100 grams (g), 0.55 moles (mol) in dry tetrahydrofuran was added dropwise 1 molar (M) vinyl magnesium bromide in tetrahydrofuran solvent (124 g, 0.94 mol) over one hour (h) at room temperature. The mixture was then stirred for 4 h at room temperature. Excess Grignard reagent was quenched by addition of acetone (200 milliliters (mL)) while the temperature of the mixture was maintained at a temperature below 20 °C. Thereafter, 2,3-dichloro-5,6- dicyano-p-benzoquinone (DDQ; 151 g, 0.67 mol) was added at once and stirred overnight.
A yellow solid precipitated out. The solid was filtered and washed with ethyl acetate (500 mL). The filtrate was concentrated under reduced pressure and the resulting crude compound was diluted with ethyl acetate (2 liters (L)). The resulting undissolved, dark, semi-solid was separated by filtration using ethyl acetate. It was further concentrated under reduced pressure to provide a crude compound, which was purified by column chromatography. The compound was eluted with 5% to 10% ethyl acetate in hexanes mixture to provide the title compound (70 g, 60%): mp 60 – 61 °C; H NMR (CDCl ) δ 3.99 (s, 3H), 5.85 (d, 1H), 6.75 (d, 1H), 6.95 (dd, 1H).
Example 4: Preparation of 2,6-dichloromethoxy-pyrimidinecarbaldehyde Cl CH 3 Cl CH Cl N A solution of 2,6-dichloromethoxyvinyl pyrimidine (50 g, 0.24 mol) in dichloromethane:methanol (4:1, 2L) was cooled to -78 °C. Ozone gas was bubbled through for 5 h. The reaction was quenched with dimethyl sulfide (50 mL). The mixture was slowly warmed to room temperature and concentrated under reduced pressure at 40 °C to provide the title compound (50.5 g, 100%). 1002485149 Example 5: Preparation of methyl 2,6-dichloromethoxy-pyrimidinecarboxylate Cl CH Cl CH Cl N Cl N CH A solution of 2,6-dichloromethoxy-pyrimidinecarbaldehyde (50 g, 0.24 mol) in methanol (1 L) and water (60 mL) was prepared. To the solution, sodium bicarbonate (400 g) was added. A 2 M solution of bromine (192 g, 1.2 mol) in methanol/water (600 mL, 9:1 v/v) was added dropwise to the pyrimidine solution over 45 minutes (min) at 0 °C while stirring the mixture. The stirring was continued at the same temperature for 1 h. Later, the mixture was stirred at room temperature for 4 h. While stirring, the reaction mixture was thereafter poured onto a mixture of crushed ice (2 L), sodium bisulfite (50 g), and sodium chloride (NaCl; 200 g). The product was extracted with ethyl acetate (1 L x 2), and the combined organic layer was dried over sodium sulfate (Na SO ) and filtered. Evaporation of the solvent under reduced pressure produced a thick material, which solidified on long standing to afford the title compound (50.8 g, 87%): ESIMS m/z 238 ([M+H] ).
Example 6: Preparation of methyl 6-aminochloromethoxy-pyrimidine carboxylate (Head C) Cl CH NH CH 3 2 3 Cl CH Cl CH A solution of methyl 2,6-dichloromethoxy-pyrimidinecarboxylate (25 g, 0.1 mol) and dimethyl sulfoxide (DMSO) was prepared. To this solution was added, at 0–5 °C, a solution of ammonia (2 equivalents (equiv)) in DMSO. This mixture was stirred at the same 0–5 °C temperature for 10 to 15 min. Later, the mixture was diluted with ethyl acetate, and the resulting solid was filtered off. The ethyl acetate filtrate was washed with a brine solution and dried over Na SO . Upon concentration, the crude product was obtained. The crude product was stirred in a minimum amount of ethyl acetate and filtered to obtain the pure compound. Additional pure compound was obtained from the filtrate which, after 1002485149 concentration, was purified by flash chromatography. This produced the title compound (11 g, 50%): mp 158 °C; H NMR (DMSO-d ) δ 3.71 (s, 3H), 3.86 (s, 3H), 7.65 (br s, 1H), 8.01 (br s, 1H).

Examples of Herbicidal Activities Herbicidal evaluations were made visually on a scale of 0 to 100 where 0 represents no activity and 100 represents complete plant death. The data are displayed as indicated in Table A. 1002485149 Table A: Percent Control Rating Conversion Table Rating Control A 95-100 B 85-94 C 75-84 D 60-74 E 45-59 F 30-44 G 0-29 Example A. Evaluation of Postemergent Herbicidal Activity Post-Emergent Test I: Seeds of test species were obtained from commercial suppliers and planted into a 13 centimeter (cm) diameter-round pot containing soil-less media mix (Metro-Mix 360 , Sun Gro Horticulture). Postemergence treatments were planted 8-12 days (d) prior to application and cultured in a greenhouse equipped with supplemental light sources to provide a 16 hour (h) photoperiod at 24–29 °C. All pots were surface irrigated.
[00356] A weighted amount, determined by the highest rate to be tested, of each compound was dissolved in 1.3 mL acetone-dimethyl sulfoxide (DMSO; 97:3, volume per volume (v/v)) and diluted with 4.1 mL water-isopropanol-crop oil concentrate (78:20:2, v/v/v) containing 0.02% Triton X-155 to obtain concentrated stock solutions. Additional application rates were obtained by serial dilution of the high rate solution into a solution containing appropriate volume of 97:3 v/v mixture of acetone and DMSO and appropriate volume of an aqueous mixture of water, isopropyl alcohol, crop oil concentrate (78:20:2, v/v/v) containing 0.02% Triton X-155.
Formulated compounds were applied using a DeVilbiss® compressed air sprayer at 2–4 pounds per square inche (psi). Following treatment, pots were returned to the greenhouse for the duration of the experiment. All pots were sub-irrigated as need to provide optimum growing conditions. All pots were fertilized one time per week by subirrigating with Peters Peat-Lite Special fertilizer (2020). 1002485149 Phytotoxicity ratings were obtained 10 days after treatment postemergence applications.

Evaluation of Preemergent Herbicidal Activity Pre-Emergent Test I: Seeds of test species were planted into round plastic pots (5-inch diameter) containing sandy loam soil. After planting, all pots were sub-irrigated 16 h prior to compound application.
[00361] Compounds were dissolved in a 97:3 v/v mixture of acetone and DMSO and diluted to the appropriate concentration in a final application solution containing water, acetone, isopropanol, DMSO and Agri-dex (crop oil concentrate) in a 59:23:15:1.0:1.5 v/v ratio and 0.02% w/v (weight/volume) of Triton X-155 to obtain the spray solution containing the highest application rate. Additional application rates were obtained by serial dilution of the high rate solution with the above application solution.
Formulated compound (2.7 mL) was pipetted evenly over the soil surface followed by incorporation with water (15 mL). Following treatment, pots were returned to the greenhouse for the duration of the experiment. The greenhouse was programmed for an approximate 15 h photoperiod which was maintained at about 23–29°C during the day and 22–28°C during the night. Nutrients and water were added on a regular basis through surface irrigation and supplemental lighting was provided with overhead metal halide 1000- Watt lamps as necessary.
Herbicidal effect ratings were obtained 14 days after treatment. All evaluations were made relative to appropriate controls on a scale of 0 to 100 where 0 represents no herbicidal effect and 100 represents plant death or lack of emergence from the soil and is presented as indicated in Table A. Some of the compounds tested, application rates employed, plant species tested, and results are given in Table 4. 1002485149 Table 4.

Evaluation of Postemergent Herbicidal Activity Post-Emergent Test II: Seeds or nutlets of the desired test plant species were planted in Sun Gro Metro-Mix 360 planting mixture, which typically has a pH of 6.0 to 6.8 and an organic matter content of about 30 percent, in plastic pots with a surface area of 64 square centimeters. When required to ensure good germination and healthy plants, a fungicide treatment and/or other chemical or physical treatment was applied. The plants were grown for 7–21 d in a greenhouse with an approximate 15 h photoperiod which was maintained at about 23–29 °C during the day and 22–28 °C during the night. Nutrients and water were added on a regular basis and supplemental lighting was provided with overhead metal halide 1000-Watt lamps as necessary. The plants were employed for testing when they reached the first or second true leaf stage.
A weighed amount, determined by the highest rate to be tested, of each test compound was placed in a 25 mL glass vial and was dissolved in 4 mL of a 97:3 v/v mixture of acetone and DMSO to obtain concentrated stock solutions. If the test compound did not dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions obtained were diluted with 20 mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, Atplus 411F crop oil concentrate, and Triton® X-155 surfactant in a 48.5:39:10:1.5:1.0:0.02 v/v ratio to obtain spray solutions containing the highest application rates. Additional application rates were obtained by serial dilution of 12 mL of the high rate solution into a solution containing 2 mL of 97:3 v/v mixture of acetone and DMSO and 10 mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, Atplus 411F crop oil concentrate, and Triton X-155 surfactant in a 48.5:39:10:1.5:1.0:0.02 v/v ratio to obtain 1/2X, 1/4X, 1/8X and 1/16X rates of the high rate.
Compound requirements are based upon a 12 mL application volume at a rate of 187 liters per hectare (L/ha). Formulated compounds were applied to the plant material with an overhead Mandel track sprayer equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.503 square meters at a spray height of 18 inches (43 cm) above the average plant canopy height. Control plants were sprayed in the same manner with the solvent blank.
[00366] The treated plants and control plants were placed in a greenhouse as described above and watered by subirrigation to prevent wash-off of the test compounds. After 14 d, the condition of the test plants as compared with that of the untreated plants was determined visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100 corresponds to complete kill and is presented as indicated in Table A. Some of the 1002485149 compounds tested, application rates employed, plant species tested, and results are given in Table 5. 1002485149 Table 5.

Evaluation of Postemergent Herbicidal Activity in Wheat and Barley Post-Emergent Test III. Seeds of the desired test plant species were planted in Sun Gro MetroMix 306 planting mixture, which typically has a pH of 6.0 to 6.8 and an organic matter content of about 30 percent, in plastic pots with a surface area of 103.2 square centimeters (cm ). When required to ensure good germination and healthy plants, a fungicide treatment and/or other chemical or physical treatment was applied. The plants were grown for 7-36 d in a greenhouse with an approximate 14 h photoperiod which was maintained at about 18 °C during the day and 17 °C during the night. Nutrients and water were added on a regular basis and supplemental lighting was provided with overhead metal halide 1000-Watt lamps as necessary. The plants were employed for testing when they reached the second or third true leaf stage.
A weighed amount, determined by the highest rate to be tested, of each test compound was placed in a 25 mL glass vial and was dissolved in 4 mL of a 97:3 v/v mixture of acetone and DMSO to obtain concentrated stock solutions. If the test compound did not dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions obtained were diluted with 20 mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, Agri-Dex crop oil concentrate, and X-77 surfactant in a 48:39:10:1.5:1.5:0.02 v/v ratio to obtain spray solutions containing the highest application rates. Additional application rates were obtained by serial dilution of 12 mL of the high rate solution into a solution containing 2 mL of 97:3 v/v mixture of acetone and DMSO and 10 mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, Agri-Dex crop oil concentrate, and X-77 surfactant in a 48:39:10:1.5:1.5:0.02 v/v ratio to obtain 1/2X, 1/4X, 1/8X and 1/16X rates of the high rate. Compound requirements are based upon a 12 mL application volume at a rate of 187 liters per hectare (L/ha). Formulated compounds were applied to the plant material with an overhead Mandel track sprayer equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.503 square meters at a spray height of 18 inches (43 cm) above the average plant canopy height. Control plants were sprayed in the same manner with the solvent blank.
The treated plants and control plants were placed in a greenhouse as described above and watered by subirrigation to prevent wash-off of the test compounds. After 21 d, the condition of the test plants as compared with that of the untreated plants was determined visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100 corresponds to complete kill and is presented as indicated in Table A. 1002485149 By applying the well-accepted probit analysis as described by J. Berkson in Journal of the American Statistical Society, 48, 565 (1953) and by D. Finney in “Probit Analysis” Cambridge University Press (1952), herbicidal injury of a specific compound at various rates can be used to calculate GR , GR , GR and GR values, which are defined 50 80 90 as growth reduction factors that correspond to the effective dose of herbicide required to provide plant growth reduction (GR) of 20 percent, 50 percent, 80 percent and 90 percent, respectively. Probit analysis was applied to data collected from multiple dose rates of individual compounds utilizing the procedures explained in the following examples. The data for some of the dose rates and analysis of all of the dose rates are captured in the following tables.
Some of the compounds tested, application rates employed, plant species tested, and results are given in Tables 7 through 11. 1002485149 Table 7: Activity of Herbicidal Compounds in Wheat and Barley

Evaluation of Preemergent Herbicidal Activity Pre-Emergent Test III. Seeds of test species were planted into square plastic pots (10 cm wide) containing sandy loam soil. After planting, all pots were sub-irrigated 16 h prior to compound application.
[00373] A weighed amount, determined by the highest rate to be tested, of each test compound was placed in a 25 mL glass vial and was dissolved in 4 mL of a 97:3 v/v mixture of acetone and DMSO to obtain concentrated stock solutions. If the test compound did not dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions obtained were diluted with 20 mL of an aqueous mixture containing water and 0.02% w/v (weight/volume) of Triton X-155 to obtain spray solutions containing the highest application rates. Additional application rates were obtained by serial dilution of 12 mL of the high rate solution into a solution containing 2 mL of 97:3 v/v mixture of acetone and DMSO and 10 mL of an aqueous mixture containing water and 0.02% w/v (weight/volume) of Triton X-155 to obtain 1/2X, 1/4X, 1/8X and 1/16X rates of the high rate. Compound requirements are based upon a 12 mL application volume at a rate of 187 liters per hectare (L/ha). Formulated compounds were applied to the soil surface with an overhead Mandel track sprayer equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.503 square meters. Control pots were sprayed in the same manner with the solvent blank.
The treated pots and control pots were placed in a greenhouse as described above and watered through surface irrigation. After 21 d, the condition of the test pots as compared with that of the untreated pots was determined visually and scored on a scale of 0 to 100 percent where 0 corresponds to no herbicidal effect and 100 corresponds to plant death or lack of emergence from the soil and is presented as indicated in Table A. 1002485149 By applying the well-accepted probit analysis as described by J. Berkson in Journal of the American Statistical Society, 48, 565 (1953) and by D. Finney in “Probit Analysis” Cambridge University Press (1952), herbicidal injury of a specific compound at various rates can be used to calculate GR , GR , GR and GR values, which are defined 50 80 90 as growth reduction factors that correspond to the effective dose of herbicide required to provide plant growth reduction (GR) of 20 percent, 50 percent, 80 percent and 90 percent, respectively. Probit analysis was applied to data collected from multiple dose rates of individual compounds utilizing the procedures explained in the following examples. The data for some of the dose rates and analysis of all of the dose rates are captured in the following tables.
Some of the compounds tested, application rates employed, plant species tested, and results are given in Table 12.

Evaluation of Postemergence Herbicidal Activity in Direct Seeded Rice Seeds or nutlets of the desired test plant species were planted in a soil matrix prepared by mixing a loam soil (43 percent silt, 19 percent clay, and 38 percent sand, with a pH of about 8.1 and an organic matter content of about 1.5 percent) and river sand in an 80 to 20 ratio. The soil matrix was contained in plastic pots with a surface area of 139.7 cm . 1002485149 When required to ensure good germination and healthy plants, a fungicide treatment and/or other chemical or physical treatment was applied. The plants were grown for 10–17 d in a greenhouse with an approximate 14-h photoperiod which was maintained at about 29 °C during the day and 26 °C during the night. Nutrients and water were added on a regular basis and supplemental lighting was provided with overhead metal halide 1000-Watt lamps as necessary. The plants were employed for testing when they reached the second or third true leaf stage.
A weighed amount, determined by the highest rate to be tested, of each test compound was placed in 25 mL glass vials and dissolved in a volume of 97:3 v/v acetone– DMSO to obtain 12X stock solutions. If the test compound did not dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions were added to the spray solutions so that the final acetone and DMSO concentrations were 16.2% and 0.5%, respectively. Spray solutions were diluted to the appropriate final concentrations with the addition of 10 mL of an aqueous mixture of 1.5% (v/v) Agri-dex crop oil concentrate. The final spray solutions contained 1.25% (v/v) Agri-dex crop oil concentrate. Compound requirements are based upon a 12 mL application volume at a rate of 187 L/ha. Formulated compounds were applied to the plant material with an overhead Mandel track sprayer equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.503 square meters (m ) at a spray height of 18 inches (43 cm) above average plant canopy height.
Control plants were sprayed in the same manner with the solvent blank.
The treated plants and control plants were placed in a greenhouse as described above and watered by sub-irrigation to prevent wash-off of the test compounds. After 20–22 d, the condition of the test plants, compared with that of the untreated plants, was determined visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100 corresponds to complete kill and is presented as indicated in Table A.
