A 25% hydrogen bromide/acetic acid (60 ml) solution was added to a solution of 2-(2,4-dichlorophenyl)-2-oxoethyl thiocyanate (5.97 g, 24.3 mmol) in acetic acid (60 ml), and the mixture was stirred at 130° C. for 2 hours. Water (120 ml) was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 6.89 g (92.0%) of the desired product as a solid.
