Procedure

A solution of 93.4 g of 3-(4-methylphenyl)-5-oxo 2-pyrrolidinepropanoic acid methyl ester and β-(4-methylphenyl)-5-oxo-2-pyrrolidinepropanoic acid methyl ester in 370 ml of 1 N aqueous sodium hydroxide solution is heated to 60° C. for four hours. Excess aqueous hydrochloric acid (1 N, 380 ml) is added and the solution is concentrated under reduced pressure to give β-(4-methylphenyl)-5-oxo-2-pyrrolidinepropanoic acid and 3-(4-methylphenyl)-5-oxo-2-pyrrolidinepropanoic acid.
