反应详情

cis-4-(Trifluoromethyl)cyclohexanecarboxylic acid (1.05 g, 5.4 mmol) and tetrahydrofuran (20 ml) were mixed and ice-cooled. A borane-tetrahydrofuran complex (10.71 ml, 10.7 mmol) was added to the mixture dropwise. After the completion of dropwise addition, the reaction mixture was stirred at room temperature overnight. 1 N hydrochloric acid was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated sodium chloride aqueous solution, dried over sodium sulfate, and concentrated to afford the title compound as a colorless oil (0.92 g, 94%).
