Procedure

2,4,6-trichloroaniline, 49.1 gm, was added to 250 ml of methylene chloride. The system was cooled to 0° C. and 34.8 ml of triethylamine was then added. After addition of the triethylamine, 21.8 ml of bromacetylbromide was added. The system was allowed to warm to room temperature and stirred there for 18 hours. The reaction was then stopped and the solvent was washed with saturated sodium bicarbonate solution. The methylene chloride layer was separated and partially stripped when a solid precipitated from solution. The solid was filtered and air dried to yield 41.4 gm of α-bromo-(2,4,6-trichlorophenyl) acetamide as a gray solid.
