Versuchsvorschrift

5-(4-carboxymethylphenylsulfonyl)thiophene-2-sulfonamide (1.6 g) was dissolved in 50 ml of tetrahydrofuran and 0.72 g of carbonyldiimidazole was added. After stirring for one hour at room temperature excess aqueous dimethylamine was added and the mixture stirred overnight. The reaction mixture was concentrated under vacuum and the residue partitioned between ethyl acetate and water. The organic phase was separated, dried over sodium sulfate and concentrated under vacuum, giving an oil weighing 1.35 g, N.M.R. (acetone, d6) δ: 2.92 (3H, s), 3.08 (3H, s), 3.84 (2H, s), 7.02 (2H, s), 7.50 (3H, m), 7.65 (1H, d), 7.90 (2H, d). The following compounds were also made by similar procedures: 5-(4-ethylcarbamoylmethylphenylsulfonyl)thiophene-2-sulfonamide, 5-[4-(2-methylcarbamoylethyl)phenylsulfonyl]thiophene-2-sulfonamide, and 5-[4-(3-dimethylcarbamoylpropyl)phenylsulfonyl]thiophene-2-sulfonamide.
