Procedure

In 30 ml of ethanol was dissolved 3.0 g of ethyl 3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butyrate. To the resulting solution was added 6 ml of concentrated aqueous ammonia. The resulting mixture was subjected to reaction at 20°-25° C. for 5 hours. Then, the solvent was removed by distillation under reduced pressure. The residue obtained was purified by a column chromatography (eluant: chloroform/methanol=20/1) to obtain 2.1 g of 3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butanamide.
