Reaction Steps

2-Chloro-4-iodoaniline (12.65 g) and phthalic anhydride (7.4 g) are dissolved in 30 mL of dimethylformamide. The solution is heated to reflux for 16 hours. The reaction mixture is diluted with diethyl ether and washed with brine to yield a precipitate which is filtered off and washed with water and diethyl ether to yield N-(2-chloro-4-iodophenyl)phthalimide as a white solid.
