Reaction Steps

A 25% hydrogen bromide/acetic acid (45 ml) solution was added to a solution of 2-(3-chlorophenyl)-2-oxoethyl thiocyanate (4.90 g, 23.2 mmol) in acetic acid (45 ml), and the mixture was stirred at 130° C. for 2 hours and at room temperature for 1 hour. Water (50 ml) was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 6.36 g (100%) of the desired product as a solid.
