After dissolving [cis-4-(trifluoromethyl)cyclohexyl]methanol (2.04 g, 10.2 mmol) in dimethylsulfoxide (30 ml), 2-iodoxybenzoic acid (4.00 g, 14.3 mmol) was added thereto and stirred at room temperature overnight. Water and ethyl acetate were added to the reaction mixture, the insoluble matter was removed by filtration, and then the filtrate was separated into layers. 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 (2.3 g, 100%).
