Procedure

To a mixed solution of ethyl (2R)-2-{4-[1-(4-heptyloxyphenyl)-5-methyl-1H-pyrrol-2-yl]phenoxy}-3-phenylpropanoate (235 mg, 0.435 mmol) in THF (7 ml) and methanol (7 ml) was added 1N aqueous potassium hydroxide solution (2 ml, 2 mmol) and the mixture was stirred for 1 hour at room temperature. The reaction solution was neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The extract was washed with water, dried over magnesium sulfate anhydride and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1) to give the object compound as an oily substance. 210 mg (yield: 94.2%)
