Procedure: 3,4-Dibromohexahydrophthalimide (0.10 mole), benzene (300 ml) and pyridine (0.11 mole) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 2,4-Dibromobenzoyl chloride (0.10 mole) is then added dropwise to the flask with stirring at room temperature. After the addition is completed the reaction mixture is heated at reflux with continued stirring for a period of about 1 hour. After this time the reaction mixture is filtered and the filtrate is washed with water. The washed filtrate is then dried over anhydrous magnesium sulfate, filtered and stripped of solvent under reduced pressure to yield the desired product N-(2,4-dibromobenzoyl)-3,4-dibromohexahydrophthalimide. equipped with a mechanical stirrer thermometer and reflux condenser After the addition is heated at reflux with continued stirring for a period of about 1 hour After this time the reaction mixture is filtered the filtrate is washed with water The washed filtrate is then dried over anhydrous magnesium sulfate filtered
