Electric Literature of 954-81-4,Some common heterocyclic compound, 954-81-4, name is N-(5-Bromopentyl)phthalimide, molecular formula is C13H14BrNO2, 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.
General procedure: Procedure M1. A mixture of the appropriate 2-(bromoalkyl)isoindoline-1,3-dione (1 equiv) with amine (pyrrolidine or morpholine) (1.1 equiv) in the presence of K2CO3 (3 equiv) was stirred in acetonitrile under reflux for 20 h. Subsequently, the solvent was evaporated under reduced pressure,producing a residue which was further dissolved in 20 mL of water and extracted with DCM(3 x 30 mL). The organic layer was dried with anhydrous Na2SO4. The solvent was then evaporated and the residue was purified by silica gel column chromatography (S3) yielding a yellow oil. The finalproduct was transformed into hydrochloride salt. The following compounds were obtained.
The synthetic route of 954-81-4 has been constantly updated, and we look forward to future research findings.
