Procedure
0.325 g of 4-bromobenzenesulfonamide was admixed with 0.82 g of dimethylformamide dimethyl acetal in 1.6 ml of dry dimethylformamide and stirred at room temperature for 90 min. For workup, the reaction mixture was admixed with 10 ml of water, and the precipitate was filtered off with suction, filtered and dried under reduced pressure. 4-Bromo-N-[1-dimethylaminomethylidene]benzenesulfonamide was obtained in a yield of 85%. Molecular weight 289.97 (C9H11BrN2O2S); retention time Rt=1.3 min. [B]; MS (ESI): 290.96 (MH+).
