Methyl 4-bromocinnamate → 3-(4-Bromophenyl)propan-1-ol

참여 물질

반응 단계

To a THF solution (0.5 M) of methyl (2E)-3-(4-bromophenyl)acrylate (1 eq.) was added, at 0° C., lithium aluminum hydride (1.0 M THF solution, 1 eq.) dropwise over a period of for 3 h. The reaction mixture was then warmed slowly to RT over 1 h. At 0° C., the reaction was carefully quenched with freshly-deoxygenated H2O. The organic layer was separated and washed with cold 10% aq. HCl. The aqueous washes were combined and back-extracted with ether. The organic extracts were then washed further with sat. aq. NaHCO3 and brine, dried over MgSO4, filtered and the filtrate concentrated in vacuo to reveal a yellow oil. Purification by way of full vacuum distillation afforded the title compound as a colorless oil.
