実験手順

In trifluoroacetic acid (3.0 mL) and water (0.3 mL) was dissolved 1-{[(5-{3-fluoro-4-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]phenyl}-4-methylpyridin-2-yl)oxy]methyl}cyclobutanecarboxylic acid (299 mg), and the solution was stirred at 50° C. for 3 hours. The reaction mixture was concentrated under reduced pressure, the residue was made a pH=4 with a saturated aqueous sodium hydrogen carbonate solution and 1N hydrochloric acid, extracted with ethyl acetate, and the organic layer was washed with a saturated brine. The organic layer was dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and isopropyl ether was added to the obtained residue. The precipitated solid was collected by filtration and dried under reduced pressure to obtain 1-{[(5-{3-fluoro-4-[5-(trifluoromethyl)-1H-imidazol-2-yl]phenyl}-4-methylpyridin-2-yl)oxy]methyl}cyclobutanecarboxylic acid (200 mg).
