Reaction Steps

To a solution of 4-aminobenzonitrile (2.36 g (20.0 mmol))in pyridine (10 ml), 4-chlorobenzenesulfonyl chloride (4.35 g (20.6 mmol)) was added under cooling in a water bath (15° C.). After 18 hours' stirring at room temperature, water (100 ml) was added to the reaction mixture and the stirring was continued to bring about separation of crystals, which were then collected by filtration and washed with water to give 4.45 g (76%) of 4-chloro-4′-cyanobenzenesulfonanilide as pale orange crystals.
