1,3-Dibromopropane → N-3-Bromopropylphthalimide

Participants

Reaction Conditions

Reaction Steps

A suspension of 18.52 g of potassium phthalimide and 200 g of 1,3-dibromopropane in 100 ml of dimethylformamide was heated under stirring at 120° C. for 6 hours to react them. Insoluble matters were then filtered off from the reaction mixture and the filtrate was then concentrated to dryness under reduced pressure. The residue was washed with hexane and then recrystallized from ethanol-water. Resulting crystals were collected by filtration, washed and then dried to obtain 13.8 g of N-(3-bromopropyl)phthalimide.
