Reaction Steps

1.45 g (14.5 mmol) of calcium carbonate and then 2.3 g (10.9 mmol) of 4-chlorobenzenesulphonyl chloride are successively added to a mixture of 1.8 g (7.37 mmol) of 3,5-dimethyl-4-[(nitromethyl)sulphonyl]aniline in 45 ml of anhydrous tetrahydrofuran. The reaction medium is stirred for 27 h at room temperature and then poured into 200 ml of water. This mixture is extracted 3 times with methylene chloride. The combined organic extracts are washed with water, dried over sodium sulphate and concentrated to dryness under reduced pressure. The residue obtained is purified by chromatography on a column of silica (eluent: methylene chloride) and then by recrystallization from chloroform, to give 0.44 g (14%) of 4-chloro-N-[3,5-dimethyl-4-[(nitromethyl)sulphonyl]phenyl]benzenesulphonamide.
