실험 절차

A solution of 1,1,1-trifluoro-4-(methylphenyl)-3-butyn-2-one (3, 10 mmol) in ethanol (100 mL) is refluxed with 4-sulfamylphenyl hydrazine hydrochloride (4, 12 mmol) for 4 h. The reaction mixture is cooled and diluted with water. The precipitated crude 4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]benzenesulfonamide is filtered and recrystallized.
