trans-Diethyl 1-benzylpyrrolidine-3,4-dicarboxylate (830 mg, 2.72 mmol) synthesized by using WO2009/027820 as a reference was dissolved in THF (24 mL). After adding lithium aluminum hydride (206 mg, 5.44 mmol) at 0° C., the solution was stirred at room temperature for 1.3 hours. The reaction mixture was further stirred at room temperature after adding sodium sulfate decahydrate, chloroform, and Celite. The mixture was filtered after adding anhydrous magnesium sulfate, and the filtrate was concentrated under reduced pressure. Hexane was added, and the solid was removed by filtration to give (trans-1-benzylpyrrolidine-3,4-diyl)dimethanol (565 mg, 93.9%).
