| titleOfInvention | Process for producing N-acylaminomethylphosphonic acid |
| abstract | (57) [Summary] [Object] The present invention provides N useful as an intermediate for the synthesis of N-phosphonomethylglycine salt known as a herbicide drug substance. -Regarding a method for producing an acylaminomethylphosphonic acid, comprising: N-methylolamide compound and phosphorus trihalide in an aprotic solvent in an amount of 0.25 to 2.5 times the molar amount of water with respect to the phosphorus trihalide. 60-160 ℃ in the coexistence of The method is characterized in that the reaction is performed by heating to the temperature of 1, and then contacted with water. [Effect] There are advantages such as a high yield, easy control of the reaction, and a simple step of separating the target product from the reaction solution. |
