N-phosphonomethylglycine(I). useful as herbicide, was prepd. by hydrolysis of compound(IV). The intermediate (IV) was prepd. by reaction of 1,3,5-tricarbohydrocarbonoxy-methy1-hexahydrotriazine(II: R,R' = monovalent hydrocarbon group) with phosphits ester(III). Thus, 1,3,5-tricarboethoxymethy1 hexahydro-1,3,5-triazine (1.38part), di-(4-methoxypheny1) - phosphite (3.53 part) and anhydrous benzene (50 ml) was refluxed for 2 hr to give compd. (I).
