Reaction Conditions

Reaction Steps

To a solution of 1.28 g (1.70 mmol) of (−)-4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-2-[1-(pyrimidin-2-yl)piperidin-4-yl]-5,6,7,8-tetrahydroquinoline, which was prepared by a method similar to that of Reference Example 15, in 8 ml of 1,4-dioxane, 4 ml of 6 N hydrochloric acid was added, and the reaction solution was stirred at 70° C. for 3 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. n-Heptane was added to the obtained residue and the precipitate was obtained by filtration to provide 0.93 g of the title compound as a white solid (yield: 86%).
