The potassium salt of 3,4,5,6-tetrachlorophthalimide (0.10 mole) and dioxane (1200 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 2,4,6-Tribromobenzoyl chloride (0.10 mole) is then added dropwise, with stirring, to the reaction mixture at room temperature. After the addition is completed the reaction mixture is heated at reflux for a period of about 1 hour. After this time the reaction mixture is filtered and the filtrate is stripped of solvent to yield the desired product N-(2,4,6-tribromobenzoyl)-3,4,5,6-tetrachlorophthalimide.
