Some common heterocyclic compound, 24566-79-8, name is N-(6-Bromohexyl)phthalimide, molecular formula is C14H16BrNO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: indolines-derivatives
General procedure: To a suspension of the corresponding secondary amine (3.22 mmol) and anhydrous K2CO3 (765 mg, 5.48 mmol) in CH3CN (20 mL) was added the intermediates 3-5 (0.60 mmol). The mixture was refluxed for 6-8 h. The solvent was removed under reduced pressure. The residue was diluted with water (30 mL) and the mixture was extracted with dichloromethane (30 mL¡Á3). The combined organic phases were washed with brine, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified on a silica gel chromatography in petroleum ether/acetone (20/1, v/v) to afford compound 7-9
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 24566-79-8, its application will become more common.
