実験手順

Methanol (1.5 mL) and a 1 N sodium hydroxide aqueous solution (0.200 mL, 0.200 mmol) were added to (4′-{1-ethyl-1-[3-methyl-4-(4,4,4-trifluoro-3-hydroxy-3-trifluoromethyl-1-butynyl)-phenyl]-propyl}-3-fluoro-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 78-(2); 30.1 mg, 0.050 mmol), and the mixture was stirred at room temperature for five hours. The reaction solution was poured into a saturated aqueous ammonium chloride solution, and then the aqueous layer was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by preparative TLC (chloroform/methanol=10/1) to give the title compound (15.6 mg, 52%).
