Procedure

In a further embodiment of the present invention, an N-acylglycine is phosphonomethylated to form N-(phosphonomethyl)glycine (I). For example, the reaction of N-acetylglycine (XVIII), phosphorous acid or phosphorous trichloride, and a source of formaldehyde produces N-(phosphonomethyl)glycine (I) (See Reaction Scheme 9).
