A 25% hydrogen bromide/acetic acid (10 ml) solution was added to a solution of 2-(3-cyanophenyl)-2-oxoethyl thiocyanate (1.0 g, 4.94 mmol) in acetic acid (10 ml), and the mixture was stirred at 130° C. for 2 hours and at room temperature for 1 hour. Water was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 990 mg (75.6%) of the desired product as a solid.
