Participants

Reaction Steps

To 40.7 mg (0.055 mmol) of (5S)-4-(4,4-Difluorocyclohexyl)-3-{(S)-fluoro[4-(trifluoromethyl)phenyl]methyl}-2-{1-[5-(3-hydroxy-3-methylbutoxy)pyrimidin-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 16, 0.28 ml of isopropyl acetate and 0.008 ml of ultrapure water were added, and the reaction mixture was stirred at room temperature to obtain a homogeneous solution. Then, 0.004 ml (0.062 mmol) of methanesulfonic acid was added thereto, and the reaction mixture was stirred at the same temperature for 90 minutes. The precipitated solid was obtained by filtration, washed with 0.04 ml of isopropyl acetate three times and then dried under reduced pressure at 40° C. to provide 38.7 mg of the title compound as a white powder (yield: 85%).
