0.98 g (3.5 mmol) of 2-amino-6-methoxy-4-phosphonomethyl-hex-3-enoic acid ethyl ester is heated under reflux in 7 ml of water for 17 hours. The reaction mixture is concentrated by evaporation and crystallised from a mixture of water and ethanol. 2-amino-6-methoxy-4-phosphonomethyl-hex-3-enoic acid having a melting point of 214° C. (decomp.) is obtained.
