Procedure

In the same manner as in Reference Example 5, starting from 0.971 g of (1S)-[(2R)-(2,4-difluorophenyl)-2-oxiranyl]ethanol and 1.0 g of 2-[4-(2,2,2-trifluoroethoxy) phenyl]-3(2H,4H)-1,2,4-triazolone, 0.825 g of 4-[(1R,2S)-2-(2,4-difluorophenyl)-2,3-epoxy-1-methylpropyl]-2-[4-(2,2,2-trifluoroethoxy)phenyl]-3(2H,4H)-1,2,4-triazolone was obtained as colorless prisms.
