실험 절차

To a solution of 68 mg (0.085 mmol) of 4-(4,4-Difluorocyclohexyl)-2-{1-[5-(ethoxymethyl)pyrimidin-2-yl]piperidin-4-yl}-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-5,6,7,8-tetrahydroquinoline, which was prepared by a method similar to that of Reference Example 21, in 1 ml of dichloromethane, 46 μl of anisole and 130 μl of trifluoroacetic acid were added, and the reaction solution was stirred at room temperature for 19 hours. Then, 100 μl of trifluoroacetic acid was further added and the reaction solution was stirred at room temperature for 1 hour. 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=98/2-70/30 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure. n-Hexane was added to the obtained residue and the precipitate was obtained by filtration to provide 34 mg of the title compound as a white solid (yield: 58%).
