Reaction Steps
A mixture of 3-(1-benzyl-2-oxopyrrolidin-4-yl)-3-oxopropanoate (24.0 g, 0.083 mole) and sodium chloride (10.6 g, 0.181 mole) in dimethylsulfoxide (105 mL)/water (4.4 mL) was heated at 135° with stirring for 16 hours. On cooling the reaction mixture was poured onto ice water (900 mL) and extracted with dichloromethane (800 mL). The organic phase was washed with water (4×500 mL) and dried (MgSO4). The solvent was removed under reduced pressure to give 4-acetyl-1-benzyl-2-pyrrolidinone (15.0 g, 83%) as a brown oil.
