Reaction Steps

197 g (1.23 mol) of bromine were slowly added dropwise, while cooling with ice, to a solution of 200 g (1.23 mol) of 2,4-dichloroaniline and 200 g (2.46 mol) of sodium thiocyanate in 1.5 1 of glacial acetic acid. Stirring was carried out for 16 hours at about 20° C., after which the solid was separated off and washed with 10% strength sodium hydroxide solution and water.
