Procedure
A flask is charged with the 1-(4-bromo-phenyl)-3-dimethylamino-propenone (1.05 g, 4.10 mmol), 4-guanidino-benzenesulfonamide (1.33 g, 6.20 mmol), and NMP (30 ml). The reaction mixture is stirred at 120° C. for 20 h. The reaction mixture is cooled to room temperature, diluted with water, and filtered. The solid residue is washed with water and dried to yield 1.66 g of a white solid. MS (ESI) m/z 405.1; HRMS: calcd for C16H13BrN4O2S+H+, 405.00153; found (ESI-FTMS, [M+H]1+), 405.00158.
