258, 1532 (1964)], but in the method (2), the equivalent mole of amine is liberated by the reaction, which requires a separation operation, which is complicated, and the yield is not very high. In method (2), the aminophosphine that can be used is, for example, HMPA [(Me2N
)3P] is limited to aminophosphine having a dialkylamino group, so it cannot be used to synthesize this kind of compounds having various substituents. In order to overcome these drawbacks, the present inventors have developed Q-(N-silyl-N-
The present invention has been completed as a result of extensive research into methods for producing (substituted) carbamoylcarboxylic acid esters.

Purification can be easily carried out by directly distilling the reaction mixture under reduced pressure or recrystallizing it. Note that this reaction dislikes water, so it is desirable to carry out the reaction under anhydrous conditions. Hereinafter, the present invention will be explained in more detail with reference to Reference Examples and Examples.
