These common heterocyclic compound, 954-81-4, name is N-(5-Bromopentyl)phthalimide, its 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. Application In Synthesis of N-(5-Bromopentyl)phthalimide
General procedure: Compound 5 (5.67g, 12mmol) was added into MeCN (50mL), and then Compound 6-9 (14.2mmol) were added, respectively. After an addition of K2CO3 (5.9g, 42.6mmol), the mixture was refluxed for 24h and followed by TLC. After the solvent was removed by distillation under reduced pressure, the residue was dissolved in EtOAc (200mL), and washed by water (3¡Á50mL). The organic phase was dried by MgSO4, and then was evaporated. The crude product was purified by column chromatography (DCM/EtOAc=20:1, Rf=0.7) to give 10-13 as white solid.
The synthetic route of N-(5-Bromopentyl)phthalimide has been constantly updated, and we look forward to future research findings.
