Procedure

A 2 N sodium hydroxide aqueous solution (0.25 mL) was added to a solution of (4′-{1-[4-(3,3-dimethyl-2-oxo-butoxy)-3-methyl-phenyl]-1-ethyl-propyl}-3-fluoro-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 103-(1); 38.6 mg, 0.0724 mmol) in methanol (2.4 mL), and the mixture was stirred for four hours. A saturated aqueous ammonium chloride 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 (38.7 mg, 99%).
