Reaction Steps

In the same manner as in Reference Example 5, starting from 543 mg of (1S)-1-[(2R)-2-(2,4-difluorophenyl)-2-oxiranyl]ethanol and 809 mg of 4-[4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl]-3(2H,4H)-1,2,4-triazolone prepared by a method described in Journal of Medicinal Chemistry, vol. 27, page 894 (1984), 2-[(1R,2S)-2-(2,4-difluorophenyl)-2,3-epoxy-1-methylpropyl]-4-[4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl]-3(2H,4H)-1,2,4-triazolone (373 mg) was obtained as colorless prisms.
