INTERMEDIATES FOR THE PREPARATION OF (N)-[2-(CARBOXYMETHOXY) ETHYL]-(N)-(CARBOXYMETHYL) GLYCINE

Document Type and Number:

WIPO Patent Application WO2000076959

Kind Code:

A3

Abstract:

Compounds represented by formula (X), wherein R and R1 independently represent H, -CH2CN or -CH2CO2X, with the proviso that R and R1 can not be both H or -CH2CO2X; and X represents hydrogen, an alkali metal or alkaline earth metal are disclosed. These compounds are useful as intermediate compounds in the preparation of N-[2-(carboxymethoxy)ethyl]-N-(carboxy-methyl) glycine. These intermediates can be formed by contacting 3-morpholinone with glycolonitrile under alkaline conditions to form an aminonitrile which can be hydrolyzed and contacted with additional glycolonitrile to form the nitrile intermediate which can be converted to N-[2-(carboxymethoxy)ethyl]-N)carboxymethyl) glycine via hydrolysis.
