(1S)-[(2R)-(2,4-difluorophenyl)-2-oxiranyl]ethanol → (2R)-2-(2,4-difluorophenyl)-2-[(1R)-1-[1-(4-trifluoromethylphenyl)-1H-1,2,4-triazol-5-yloxy]ethyl]oxirane

Participants

Reaction Steps

In the same manner as in Reference Example 5, starting from 2.49 g of (1S)-1-[(2R)-2-(2,4-difluorophenyl)-2-oxiranyl]ethanol and 2.52 g of 2-(4-trifluoromethylphenyl)-3(2H,4H)-1,2,4-triazolone, 4-[(1R,2S)-2-(2,4-difluorophenyl)-2,3-epoxy-1-methylpropyl]-2-(4-trifluoromethylphenyl)-3(2H,4H)-1,2,4-triazolone (1.13 g) and 618 mg of (2R)-2-(2,4-difluorophenyl)-2-[(1R}-1-[1-(4-trifluoromethylphenyl)-1H-1,2,4-triazol-5-yloxy]ethyl]oxirane were obtained.
