2-(3-bromobutyl)isoindole-1,3-dione

Conditions: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1,3 dibromobutane (10.8 g, 0.05 mol) and potassium phthalimide (9.25 g, 0.05 mol) were added to dry N,N dimethylformamide (100 ml) and the resulting mixture stirred at ambient temperature (20° C.) overnight. The resulting mixture was filtered to remove any solid and the solvent removed from the filtrate to give a colourless oil. The product, N-(3-bromobutyl)phthalimide, was isolated from the oil by flash chromatography on a silica gel column using silica gel, 230 to 400 US mesh (0.062 mm to 0.037 mm) eluted with 2% methanol in dichloromethane as a brown solid in a yield of 7.9 g (55.7%). The resulting mixture was filtered to remove any solid the solvent removed from the filtrate to give a colourless oil
