실험 절차

A 1 N sodium hydroxide aqueous solution (0.296 mL, 0.296 mmol) was added to a solution of (4′-{1-[4-(3,3-dimethyl-2-oxo-butoxy)-3-methyl-phenyl]-1-ethyl-propyl}-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 50-(1); 50.7 mg, 0.099 mmol) in methanol-tetrahydrofuran (1:1, 4 mL), and the mixture was stirred at 60° C. for two hours. The reaction mixture was then poured into 0.5 N hydrochloric acid aqueous 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 (43.3 mg, 87%).
