Reaktionsschritte
A solution of 4-nitrobenzoylchloride (1.85 g, 1 eq.) in acetonitrile (20 ml) was added to a solution of 4-aminomethyl-benzenesulfonamide hydrochloride (4.44 g, 2 eq.) and triethylamine (2.78 ml, 2 eq.) in acetonitrile (40 ml) at 0° C. under inert atmosphere. After the addition was completed, the mixture was warmed to rt and stirred for 3 d. Water was added and the mixture was concentrated under reduced pressure. The resulting precipitate was filtered off and washed with water and methanol to yield 2.86 g (85%) of 4-nitro-N-(4-sulfamoylbenzyl)-benzamide.
