실험 절차

(2R,3S)-2-(2-Fluorophenyl)-3-methyl-2-(1H-1,2,4-triazol-1-yl)methyloxirane (1.5 g), 2.66 g of 1-[4-(1,1,2,2-tetrafluoroethoxy)phenyl]-2(1H,3H)-imidazolone and 0.386 g of 60% sodium hydride in oil were added to 25 ml of N,N-dimethylformamide. The mixture was stirred at 80° C. for 20 hours. After cooling, the reaction mixture was added to 100 ml of water and extracted with ethyl acetate (50 ml×2). The extract was washed with water, dried over anhydrous magnesium sulfate and then distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=3/2) to give 0.27 g of 1-[(1R,2R)-2-(2-fluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]-3-[4-(1,1,2,2-tetrafluoroethoxy)phenyl]-2(1H,3H)-imidazolone as a colorless powder.
