Procedure

10% palladium carbon (16 mg) was added to a solution of [5-(4-{1-ethyl-1-[4-(1-hydroxy-cyclopentylethynyl)-3-methyl-phenyl]-propyl}-phenyl)-pyridin-3-yl]-acetic acid methyl ester (Example 148-(1); 16.4 mg, 0.033 mmol) in methanol (0.2 mL), and the mixture was stirred in a hydrogen atmosphere for 19 hours. The reaction solution was filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane:ethyl acetate=3:1) to give the title compound (13.1 mg, 79%).
