Versuchsvorschrift

Methanol (7 mL) was added to ethyl 1-[({4-methyl-6′-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]-3,3′-bipyridin-6-yl}oxy)methyl]-cyclobutanecarboxylate (343 mg), 1N aqueous sodium hydroxide solution (2.9 mL) was further added to the mixture and the resulting 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, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 1-[({4-methyl-6′-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]-3,3′-bipyridin-6-yl}oxy)methyl]-cyclobutanecarboxylic acid.
