Participants

Reaction Steps

In dichloromethane (4 ml) was dissolved (2R,3R)-3-chlorosulfonyl-2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-2-butyl acetate (125 mg). To the solution was added, under ice-cooling, n-butylamine (23 mg). The reaction mixture was stirred for 20 minutes under ice-cooling, which was concentrated. The concentrate was subjected to a silica gel chromatography (eluent: hexane/ethyl acetate=1/2→ethyl acetate) for purification to give, as the first eluate, N-butyl-3- (2,4-difluorophenyl)-4-(1H-1,2,4-triazol-1-yl) -2-butene-2-sulfonamide (isomer B, Compound 33, 10 mg) as a colorless oily substance, and, as the second eluate, N-butyl-3-(2,4-difluorophenyl)-4-(1H-1, 2,4-triazol-1-yl) -2-butene-2-sulfonamide (isomer A, Compound 32, 45 mg) as a colorless solid substance.
