Reaction Steps

In ethanol (50 mL) and tetrahydrofuran (20 mL) was dissolved 5-[4-(2,2-difluoroethenyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]-2-{4-[(4-methoxybenzyl)oxy]phenyl}pyridine (0.84 g), 10% palladium-carbon (50% water contained, 395 mg) was added to the solution, and the mixture was stirred under hydrogen atmosphere for 24 hours. The reaction mixture was filtered by using a membrane filter, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography to obtain 4-{5-[4-(2,2-difluoroethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]pyridin-2-yl}phenol (373 mg).
