Reactions similar to those of Example 3 were performed except for using 4.5 μl (0.069 mmol) of methanesulfonic acid instead of 47% hydrobromic acid salt and using 2.5 ml of tert-butyl methyl ether instead of methyl ethyl ketone, and from 51.8 mg (0.069 mmol) of (5S)-4-(4,4-Difluorocyclohexyl)-3-{(S)-fluoro[4-(trifluoromethyl)phenyl]methyl}-2-(1-{5-[3-hydroxy-2-(hydroxymethyl)-2-methylpropoxy]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 19, 29 mg of the title compound was obtained as a white powder (yield: 50%).
