Reaction Steps

A solution of 4-(trifluoromethyl)-2-(6-(trifluoromethyl)pyridin-3-yloxy)benzoic acid (28 mg, 81 μmol), HATU (31 mg, 81 μmol), and Et3N (11 μL, 81 μmol) in DMF (1.0 mL) was stirred at room temperature for 5 min, then 5-aminopyridine-3-sulfonamide (14 mg, 81 μmol) was added. The reaction was stirred at room temperature then overnight at 70° C. The reaction was purified by reverse phase HPLC (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)) to give N-(5-sulfamoylpyridin-3-yl)-4-(trifluoromethyl)-2-(6-(trifluoromethyl)pyridin-3-yloxy)benzamide. LC/MS: m/z 507.3 (M+H)+ at 1.61 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
