Benzenesulfonamide, 3-amino- → N-(3-sulfamoylphenyl)-4-(trifluoromethoxy)benzamide

Participants

Reaction Steps

To a solution of 3-amino-benzenesulfonamide (17 mg, 0.10 mmol) in pyridine (1 mL) was added 4-trifluoromethoxy benzoyl chloride (16 μL, 0.10 mmol). The reaction was stirred at room temperature for 15 h and purified by preparative reverse phase HPLC using 10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA) to give N-(3-(aminosulfonyl)phenyl)-4-(trifluoromethoxy)benzamide. LC/MS: m/z 360.9 (M+H)+ at 3.02 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
