120 °C

172.5 g (1 mol) of 4-amino-1-chloro-2-nitro-benzene are dissolved in 400 ml pyridine with heating. 193 g (1.09 mol) of benzene sulfochloride are slowly added dropwise, followed by heating for 1 hour at 120° C. (bath temperature). Subsequently, the solution is cast onto ice, and the 1-chloro-2-nitro-4-benzene-sulfonamido-benzene is evacuated in a vacuum. The compound is recrystallized from ethanol/water.
