Procedure
Methanol (7 mL) and 1N aqueous sodium hydroxide solution (2.6 mL) were added to ethyl 1-[({5′-chloro-4-methyl-6′-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]-methyl}-1H-imidazol-2-yl]-3,3′-bipyridin-6-yl}oxy)methyl]cyclobutanecarboxylate (327 mg), and the mixture was refluxed for 1 hour. Methanol was distilled off under reduced pressure, and the residue was neutralized by 1N hydrochloric acid. The mixture was extracted with ethyl acetate, the organic layer was washed with a saturated brine, and dried over anhydrous magnesium sulfate. The mixture was concentrated under reduced pressure to obtain 1-[({5′-chloro-4-methyl-6′-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]-3,3′-bipyridin-6-yl}oxy)methyl]-cyclobutanecarboxylic acid.
