Procedure

Trifluoroacetic acid (0.20 mL) was added to a solution of [5-(4-{1-ethyl-1-[3-methyl-4-(4,4,4-trifluoro-3-methoxymethoxy-3-trifluoromethyl-1-butynyl)-phenyl]-propyl}-2-methyl-phenyl)-pyridin-3-yl]-acetic acid methyl ester (Example 80-(1); 36.0 mg, 0.0566 mmol) in dichloromethane (1.0 mL) at 0° C., and the mixture was stirred at room temperature for three hours. A saturated aqueous sodium bicarbonate solution was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound (34.3 mg, 99%).
