실험 절차

(2R,3S)-2-(2-Fluorophenyl)-3-methyl-2-(1H-1,2,4-triazol-1-yl)methyloxirane (2.34 g), 1-[4-(2H-2-tetrazolyl)-phenyl]-2(1H,3H)-imidazolone (2.28 g) and cesium carbonate (powder: 6.52 g) were added to 1-methyl-2-pyrrolidone (100 ml), and the mixture was heated at 80° C. for 18 hours with stirring. The reaction solution was cooled, diluted with * ethyl acetate (200 ml) and added to ice water (200 ml) to separate the ethyl acetate layer. The aqueous layer was extracted with ethyl acetate (100 ml). The combined ethyl acetate layers were washed with 1N-hydrochloric acid (100 ml×2) and a saturated aqueous solution of sodium chloride (100 ml) successively. The ethyl acetate layer was dried over anhydrous magnesium sulfate and distilled under reduced pressure to remove the solvent. The residue was purified by silica gel chromatography (eluent: hexane/acetone=1/1) to give 1-[(1R,2R)-2-(2-fluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]-3-[4-(2H-2-tetrazolyl)phenyl]-2(1H,3H)-imidazolone (Compound 40; 0.494 g) as a colorless crystalline powder.
