Procedure

Ethyl 2-fluoropropionate and 1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethan-1-one were treated in the same manner as in Reference Example 7, and the residue thus obtained was purified by a column chromatography (eluant: ethyl acetate/toluene=1/4) to obtain ethyl 3-(2,4-difluorophenyl)-2-fluoro-3-hydroxy-2-methyl-4-(1H-1,2,4-triazol-1-yl)butyrate (one of the diastereomers).

Workup

  1. customthe residue thus obtained
