Procedure

To a solution of 4.80 g (7.11 mmol) of (−)-4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-5-[(4-methoxybenzyl)oxy]-7,7-dimethyl-2-(piperidin-4-yl)-5,6,7,8-tetrahydroquinoline, which was prepared by a method similar to that of Reference Example 10, in 16 ml of 1,4-dioxane, 1.40 g (7.24 mmol) of 5-bromo-2-chloropyrimidine and 1.6 ml (9.4 mmol) of diisopropylethylamine were added, and the reaction solution was stirred at 80° C. for 3 hours. After completion of the reaction, the reaction solution was poured into 40 ml of 0.5 N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution, saturated sodium hydrogencarbonate aqueous solution and saturated sodium chloride aqueous solution in order 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 5.09 g of the title compound as a white solid (yield: 86%).
