Reaction Steps

A suspension of ethyl 1-benzyl-2-methyl-4-oxo-3-pyrrolidinecarboxylate (3.4 g, 13 mmol) in water (95 ml) and sulfuric acid (5 ml) was heated to 90° C. overnight. The mixture was allowed to cool was neutralized with sodium carbonate, extracted with methylene chloride. The combined organic layer filtered through a plug of silica gel and concentrated to give 1-benzyl-5-methyl-3-pyrrolidinone (1.13 gm, 46%) as a yellow oil, MS (M+H)+=190.
