실험 절차

A 1 N sodium hydroxide aqueous solution (0.131 mL, 0.131 mmol) was added to a solution of (4′-{1-ethyl-1-[3-methyl-4-(4,4,4-trifluoro-3-hydroxy-3-trifluoromethyl-butyl)-phenyl]-propyl}-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 47-(1); 25.9 mg, 0.044 mmol) in methanol-tetrahydrofuran (1:1, 3 mL), and the mixture was stirred at room temperature overnight. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution, followed by extraction with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (chloroform:methanol=10:1) to give the target compound as a colorless oil (19.7 mg, 77%).
