Procedure

To a solution of 94 mg (0.12 mmol) of 4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-2-[1-(5-formylpyrimidin-2-yl)piperidin-4-yl]-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-5,6,7,8-tetrahydroquinoline, which was prepared by a method similar to that of Reference Example 16, in 0.6 ml of ethanol, 5.0 mg (0.13 mmol) of sodium borohydride was added, and the reaction solution was stirred at 0° C. for 2 hours. After completion of the reaction, saturated ammonium chloride aqueous solution was poured into the reaction solution and the reaction solution was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and dried with anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The obtained residue was subjected to silica gel column chromatography [n-hexane/ethyl acetate=100/0-60/40 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 89 mg of 4-(4,4-difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-2-[1-[5-(hydroxymethyl)pyrimidin-2-yl]piperidin-4-yl]-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-5,6,7,8-tetrahydroquinoline.
