Reaction Steps
To a solution of 1,5-dibromopentane (9.00 ml, 65.22 mmol) dissolved in DMF (100 ml) was added potassium phthalimide (12.08 g, 65.22 mmol) at room temperature, and the reaction mixture was stirred for 24 hours. After the reaction was completed, distilled water was added, and the resulting reaction mixture was stirred for 10 minutes and extracted with ethyl acetate three times. Then, the organic phase was washed with a saline solution, dried with anhydrous magnesium sulfate and distilled under reduced pressure. The resulting residue was subjected to silica gel column chromatography (eluent: ethyl acetate:hexane=1:3) to give the target compound (10.6 g, 55%).
