Procedure

To a cold (0° C.) suspension of lithium aluminum hydride (2.44 g, 64 mmol) in THF (40 mL) was added methyl 1-benzyl-5-oxo-3-pyrrolidinecarboxylate (5.00 g, 21 mmol). The reaction mixture was stirred at room temperature for 5 hrs. To the reaction mixture were added water (2.5 mL), 15% aqueous sodium hydroxide solution (2.5 mL), and water (7.5 mL), successively. The mixture was filtered through Celite®. The filtrate was concentrated under reduced pressure to give (1-benzyl-3-pyrrolidinyl)methanol. (4.16 g, yield; quant.)
