These common heterocyclic compound, 588-63-6, name is (3-Bromopropoxy)benzene, 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. Recommanded Product: 588-63-6
Intermediate 110 1,1-Dimethylethyl (2/?,4S)-4-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}-2-({[3-(phenyloxy)propyl]oxy} methyl)- 1 -pyrrolidinecarboxylate1 ,1-Dimethylethyl (2R,4S)-4-{[(1 ,1-dimethylethyl)(dimethyl)silyl]oxy}-2-(hydroxymethyl)-1- pyrrolidinecarboxylate (0.6 g, 1.810 mmol) was diluted in THF (1 ml) to give a colorless solution. The resulting mixture was cooled down to 0 0C under argon. Then sodium hydride (0.217 g, 9.05 mmol) in THF (2ml_) was added to give a white suspension followed by [(3-bromopropyl)oxy]benzene 3-bromopropyl phenyl ether (0.779 g, 3.62 mmol) in THF (1 ml). The resulting mixture was stirred at rt over the week end (96 h).The reaction was then quenched by addition of water at 0 0C. The THF was removed in vacuo and the resulting crude was diluted in DCM and washed with 0.1 M HCI, sat NaHCOs using a hydrophobic frit. The organic layer was then concentrated in vacuo to yield a colorless oil. This resulting oil was loaded onto a 5 g silica SPE cartridge, then eluted sequentially with hexane DCM and EA. The corresponding fractions were combined and evaporated to afford the title compound (0.45 g, 53percent). LC-MS: m/z, 466 (M+H), rt 1.67 min.
The synthetic route of (3-Bromopropoxy)benzene has been constantly updated, and we look forward to future research findings.
