1,3-Dibromopropane → N-3-Bromopropylphthalimide

Participants

Reaction Steps

90 g of potassium phthalimide was mixed with 300 ml of dimethylacetamide and stirred. 74 ml of 1,3-dibromopropane was added to the system. The system was then allowed to undergo reaction at a temperature of 120° C. over 4 hours. The reaction solution was poured into 1 l of water. The resulting crystals were filtered off with suction. The crude crystals were recrystallized from ethanol to obtain 100 g of N-(3-bromopropyl)-phthalimide (7). (Yield: 77%; m.p. 65° C.)
