Reaction Steps

To a solution of pyrrolidin-3-one hydrochloride (7.40 g, 60.9 mmol) in DCE (122 mL) was added ethyl acetate (23.9 mL, 137 mmol) followed by benzyl chloride (8.63 g, 68.2 mmol) at ambient temperature. The reaction was heated to 70° C. for 2 hours. The reaction was cooled, diluted with DCM (100 mL), water (100 mL), the layers were separated, and the organic layer was dried (MgSO4), filtered and concentrated under reduced pressure to give 1-benzylpyrrolidin-3-one (10.01 g, 57.2 mmol, 93.9% yield).
