A method for the production of N-phosphonomethylglycine which comprises reacting a 2-oxazolidone starting compound of the formula <IMAGE> with p-formaldehyde, then adding a substituted phosphorus compound of the formula PXYZ wherein X is halogen, and Y and Z are independently selected from the group consisting of halogen, alkoxy having from 1-10 carbon atoms, and aryloxy, said reaction being conducted in the presence of a low molecular weight carboxylic acid solvent for the reactants, at a combination of time and temperature sufficient to cause the reaction to go to completion, and converting the 2-oxo-3-oxazolidinyl methyl phosphonic acid thus formed to N-phosphonomethylglycine.
