Procedimiento

Gaertner, U.S. Pat. No. 3,927,080, describes the production of glyphosate by the acid hydrolysis of N-t-butyl-N-phosphonomethylglycine or its esters. Tertiary butylamine is reacted with a bromoacetate ester to produce an ester of N-t-butylglycine which is in turn reacted with formaldehyde and phosphorous acid to produce the N-t-butyl-N-phosphonomethylglycine precursor.
