実験手順
4-[5-(4-Methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]benzenesulfonamide (0.60 g, 1.57 mmol) was heated in 2 mL acetyl chloride and 2 mL acetic acid at reflux for 2 h. An additional 2 mL acetyl chloride was added and the mixture was heated to reflux for an additional 5 h. The mixture was cooled and concentrated. Recrystallization from ether/hexane furnished the product as a white solid: Anal. Calc'd for C19H16N3O3SF3: C, 53.90; H, 3.81; N, 9.92; S, 7.57. Found: C, 54.04; H, 3.80; N, 9.93; S, 7.66.
