Reaction Steps

To a solution of 145 mg (0.224 mmol) of (5S)-4-(4,4-Difluorocyclohexyl)-3-{(S)-fluoro[4-(trifluoromethyl)phenyl]methyl}-2-[1-(5-hydroxypyrimidin-2-yl)piperidin-4-yl]-7,7-dimethyl-5,6,7,8-tetrahydroquinolin-5-ol, which was prepared by a method similar to that of Reference Example 23, in 0.7 ml of N,N-dimethylformamide, 130 mg (0.445 mmol) of 3-(methylsulfonyl)propyl p-toluenesulfonate and 135 mg (0.977 mmol) of potassium carbonate were added, and the mixture was stirred at 80° C. for 4 hours. 44 mg (0.337 mmol) of 2-chloro-5-hydroxypyrimidine was further added thereto, and the mixture was stirred at 80° C. for 3 hours. After completion of the reaction, the reaction solution was poured into water and extracted with toluene 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=55/45-25/75 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 137.0 mg of the title compound as a white solid (yield: 80%).
