Procedure

An aqueous solution of 45 parts ammonium hydroxide is stirred and chilled with an ice bath, while 24.4 parts benzyl methyl carbomethoxyphosphonate is added slowly. Stirring is continued until a clear solution is obtained. Unreacted ammonium hydroxide and water are removed from the mixture under reduced pressure, leaving as a solid residue ammonium monobenzyl carbamoylphosphonate, m.p. 186, after recrystallization from ethanol.
