Procedure

To a solution of 118 mg (0.141 mmol) of 4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-2-{1-[5-(1-hydroxy-3-methylbutyl)pyrimidin-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 27, in 2 ml of 1,4-dioxane, 2 ml of 2 N hydrochloric acid was added, and the reaction solution was stirred at 100° C. for 3.5 hours. After completion of the reaction, the reaction solution was poured into saturated sodium hydrogencarbonate aqueous solution and 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=92/8-88/12 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 72 mg of the title compound as a white solid (yield: 73%).
