trans-4-Aminocyclohexanecarboxylic acid (314 mg, 2.19 mmol) was gradually added to sodium bis(2-methoxyethoxy)aluminum hydride-toluene solution (65 wt %, 3.0 mL) in toluene (3 mL) at 75° C., and the reaction mixture was stirred for 7 hours. The reaction mixture was allowed to cool to room temperature and stirred with 1 M aqueous sodium hydroxide (20 mL) at 80° C. for 10 minutes. The reaction mixture was allowed to cool to room temperature and partitioned between water and toluene, and the aqueous layer was extracted with chloroform three times. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound as a colorless solid (170 mg, yield 60%).
