Procedure

A mixture of methyl tetronate (2.0 g, 17.5 mmol) and pyrrolidine (4.0 mL, 48 mmol) in EtOH (20 mL) was heated at reflux for 2 hours. The mixture was cooled to room temperature, and evaporated to dryness. The resulting solid was recrystallized with benzene/hexanes to give 4-pyrrolidin-1-ylfuran-2(5H)-one as white crystals. Yield: 2.60 g, 96%.
