Participants

Reaction Steps

To a solution of 5.00 g (0.032 mol) of 3-amino-2-carbomethoxythiophene dissolved in 40 mL of chloroform was added 7.73 mL (0.032 mol) of pyridine followed by 6.57 g (0.032 mol) of p-methoxybenzenesulfonyl chloride. The reaction mixture was stirred at room temperature for 5 h and then washed with 3N HCl and water. The organics were then dried over Na2SO4, filtered and concentrated in vacuo. The resulting cream colored solid was washed with ether and dried in vacuo to provide 6.89 g (66%) of the desired sulfonamide. Electrospray Mass Spec 328.2 (M+H).
