Reaction Steps

Dissolve N-(3-chloro-2-methyl-phenyl)-acetamide (120.0 g, 0.653 mol) in acetic acid and cool to 0° C. Add bromine (313.3 g, 1.96 mol) dropwise over 30 min via an addition funnel. Stir for 17 h while allowing the reaction to warm to room temperature. Pour the reaction into 1 L of ice, and filter. Rinse the filter cake with 4 L of water. The title product is isolated in 93.6% yield (160.6 g) as a white solid. MS: MS (ESI−): 262 (M−1)−. MS (ESI+): 263 (M+1)+.
