Reaction Steps

A solution of 6-tert-butylpyridine-3-carboxylic acid (18 mg, 0.10 mmol) and HATU (38 mg, 0.10 mmol) in DMF (1 mL) was stirred at room temperature for 3 minutes. To this solution was added 3-amino-benzenesulfonamide (17 mg, 0. 10 mmol) and triethylamine (28 μL, 0.20 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 6-tert-butyl-N-(3-(aminosulfonyl)phenyl)pyridine-3-carboxamide. LC/MS: m/z 334.3 (M+H)+ at 1.99 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
