Methyl 6-{3-[3,5-bis(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidin-1-yl}-4-(trifluoro-methyl)nicotinate (1.21 g), sodium hydroxide (0.26 g) and water (5 ml) were added to ethanol (40 ml) and stirred at room temperature for 1 day. The solvent was distilled off under reduced pressure, diluted hydrochloric acid and t-butyl methyl ether were added and then extracted. The target compound (1.11 g) was obtained by concentration under reduced pressure.
