Versuchsvorschrift
In the same manner as in Reference Example 5, starting from 1.35 g of (1S)-1-[(2R)-2-(2,4-difluorophenyl)-2-oxiranyl]ethanol and 963 mg of 4-(4-fluorophenyl)-3(2H,4H)-1,2,4-triazolone, 583 mg of 2-[(1R,2S)-2-(2,4-difluorophenyl)-2,3-epoxy-1-methylpropyl]-4-(4-fluorophenyl)-3(2H,4H)-1,2,4-triazolone was obtained as colorless needles.
