Process for the production of 4-hydroxy-2-oxoyrrolidin-1-yl-acetamide, a cerebrally active pharmaceutical agent. A 4-halo-3-alkoxy-butenoic acid ester is reacted with glycine to new intermediate products of the formula: ##STR1## There is further by acid hydrolysis of the alkoxy group, subsequent hydrogenation, esterification of the carboxyl function and finally conversion to the end product by reaction with ammonia.
