反応手順
A solution of 2-(2-methylpyridin-3-yloxy)-4-(trifluoromethyl)benzoic acid TFA salt (54 mg, 0.13 mmol) and HATU (50 mg, 0.13 mmol) in DMF (1 mL) was stirred at room temperature 3 min. To this solution was added 3-amino-benzenesulfonamide (23 mg, 0.13 mmol) and triethylamine (46 μL, 0.33 mmol). The reaction was stirred at room temperature for 16 h and purified by preparative reverse phase HPLC using 10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA) to give 2-(2-methylpyridin-3-yloxy)-N-(3-sulfamoylphenyl)-4-(trifluoromethyl)benzamide. LC/MS: m/z 452.3 (M+H)+ at 1.07 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
