Procedure
In the same manner as in Reference Example 5, starting from 1.36 g of (1S)-1-[(2R)-2-(2,4-difluorophenyl)-2-oxiranyl]ethanol and 1.32 g of 1-(4-trifluoromethoxyphenyl)-2(1H,3H)-imidazolone, 1-[(1R,2S)-2-(2,4-difluorophenyl)-2,3-epoxy-1-methylpropyl]-3-(4-trifluoromethoxyphenyl)-2(1H,3H)-imidazolone (0.60 g) and 0.46 g of (2R)-2-(2,4-difluorophenyl)-2-[(1R)-1-[1-(4-trifluoromethoxyphenyl)-2-imidazolyloxy]ethyl]oxirane were obtained.
