As the reducing agent used in the above reduction reaction, a wide variety of known reducing agents can be used, but it is preferable to use hydrogen compounds such as sodium boron hydride and lithium tri-tert-butoxyaluminum. The amount of the reducing agent to be used is not particularly limited and can be appropriately selected within a wide range, but it is desirable to use the reducing agent in an amount of 0.1 to 5 times the mole of the compound of formula (■). This reduction reaction is usually carried out in an organic solvent. Examples of organic solvents include aliphatic alcohols such as methanol, ethanol, and isopropanol, and aliphatic ethers such as tetrahydrofuran, dioxane, and ethyl ether. The reaction temperature for this reaction is not particularly limited and is appropriately selected within a wide range up to the boiling point of the solvent, but is usually 10 to 70°C, preferably 30 to 50°C. Further, the reaction time is usually 1 to 3 hours. The compounds of the present invention are easily purified by applying conventional means such as filtration, concentration, extraction, etc.

The reaction mixture was cooled to room temperature, a small amount of acetic acid was added, and the mixture was stirred. After about 3 minutes of generation of after-gas, filter and separate to remove insoluble matter. The Oki liquid is concentrated under reduced pressure and methanol is distilled off.
When the concentrated residue is distilled under reduced pressure at 0.1 Tf$LHg, the fraction 2-methoxycarbonyl-3-
