Reaction Steps

A mixture of 100 mg of ethyl 3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butyrate and 370 mg of 4-chloroaniline was subjected to reaction at 150°-160° C. for 5 hours. The reaction mixture was cooled to room temperature. Thereto were added 10 ml of ethyl acetate and 5 ml of water. The resulting solution was adjusted to pH 2.0 with 6N hydrochloric acid. The organic layer was separated, washed with a saturated aqueous sodium chloride solution, and then dried over anhydrous magnesium sulfate. Thereafter, the solvent was removed by distillation under reduced pressure. The residue obtained was purified by a column chromatography (eluant: toluene/ethyl acetate=1/1) to obtain 30 mg of N-(4-chlorophenyl)-3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butanamide.
