Sodium Iodide → 2-(3-Iodo-propyl)-isoindole-1,3-dione

Participants

Reaction Steps

To a solution of 15 g (100 mmol) of sodium iodide in 120 ml of acetone was added 3 g (11 mmol) of N-(3-bromopropyl)phthalimide and the mixture was heated at reflux for 30 minutes. The cooled mixture was filtered and evaporated. The residue was partitioned between 50 ml of diethyl ether and 50 ml of water. The organic phase was dried over magnesium sulfate, filtered and evaporated to give 2.6 g (75%) of N-(3-iodopropyl)phthalimide as a white solid. [Mass spectrum (ESI) MH+ =316].
