Procedure

A 1 N sodium hydroxide aqueous solution (0.251 mL, 0.251 mmol) was added to a solution of [5-(4-{1-ethyl-1-[4-(4-hydroxy-tetrahydro-pyran-4-ylethynyl)-3-methyl-phenyl]-propyl}-2-methyl-phenyl)-pyridin-3-yl]-acetic acid methyl ester (Example 132-(2); 44.0 mg, 0.084 mmol) in methanol-tetrahydrofuran (1:1, 4 mL), and the mixture was stirred at room temperature for two hours. Then, the reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (ethyl acetate:methanol:water=4:1:0.3) to give the target compound as a colorless oil (40.2 mg, 94%).
