Reaction Steps

3.7 g of 1,5-dibromopentane and 4.8 g of phthalimide potassium were stirred at 150° C. for 3 hours in 15 ml of DMF. After the DMF was evaporated under reduced pressure, the residue was added with water and ethyl acetate and separated. The organic layer was dried over sodium sulfate and the solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate) to obtain 4.5 g of the title compound (yield: 75%).
