Procedure

1-[(1R,2S)-2-(2-Fluorophenyl)-2-hydroxy-3-methanesulfonyloxy-1-methylpropyl]-3-[4-(1H-1-tetrazolyl)phenyl]-2(1H,3H)-imidazolone (200 mg) was dissolved in dimethylformamide (10 ml), to which 1H-1,2,4-triazole (83 mg) and potassium carbonate (168 mg) were added, and the mixture was heated at 50° C. for 20 hours. The reaction solution was diluted with ethyl acetate (30 ml), washed with water (15 ml), 1N-hydrochloric acid (15 ml×2) and a saturated aqueous solution of sodium chloride (15 ml). The organic layer was dried over magnesium sulfate and distilled under reduced pressure to remove the solvent. The residue was purified by silica gel chromatography (eluent:ethyl acetate). The desired fraction was concentrated and recrystallized from a mixture of ethyl acetate and diisopropyl ether to give 1-[(1R,2R)-2-(2-fluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl-3-[4-(1H-1-tetrazolyl)phenyl]-2(1H,3H) -imidazolone (Compound 44, 65 mg) as a colorless crystalline powder.
