Procedure

To a solution of 2,4,6-trimethylaniline (70 mg, 0.518 mmol) in dichloromethane (0.20 mL) and triethylamine (72 □L, 0.52 mmol) was added 3-benzenesulfonylamino-thiophene-2-carboxylic acid chloride (134 mg, 0.444 mmol). The resulting mixture was allowed to stir overnight at room temperature under a nitrogen atmosphere. The reaction mixture was applied directly to silica gel, (9:1 hexane/ethyl acetate, gradient to 4:1 hexane ethyl acetate). The compound was then precipitated from hexanes and dichloromethane to give 3-benzenesulfonylamino-thiophene-2-carboxylic acid (2,4,6-trimethylphenyl) amide as a white solid (0.028 g, 16%).
