Procedure

To 377 mg (0.559 mmol) of (5S)-4-(4,4-Difluorocyclohexyl)-3-{(S)-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, 127 mg (0.466 mmol) of 2-chloro-5-[(2,2,5-trimethyl-1,3-dioxan-5-yl)methoxy]pyrimidine, which was prepared by a method similar to that of Reference Example 17, and 154 mg (1.11 mmol) of potassium carbonate, 1 ml of 1,4-dioxane was added, and the reaction mixture was stirred at 120° C. for 26 hours. After completion of the reaction, water was added to the reaction solution and the reaction solution was extracted with ethyl acetate twice. The obtained organic phases were combined and washed with saturated sodium chloride aqueous solution, and then the solvent was distilled off under reduced pressure. The obtained residue was subjected to silica gel column chromatography [n-hexane/ethyl acetate=89/11-68/32 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 391 mg of the title compound as a foam (yield: 92%).
