실험 절차

To a solution (13 mL) of 1-(2-{2-cyclopentyl-1-[4-(methylsulfonyl)phenyl]ethyl}-1H-imidazol-5-yl)-2-methylpropan-1-one (0.507 g) in acetonitrile was added xenon difluoride (0.440 g), and the mixture was heated under reflux for 4 hr. The reaction mixture was diluted with ethyl acetate, washed successively with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=5:95-40:60, volume ratio) and recrystallized from diethyl ether-hexane to give the title compound (0.07 g, yield 13%) as colorless crystals. melting point 161-162° C.
