Application of 16532-79-9, These common heterocyclic compound, 16532-79-9, name is 4-Bromophenylacetonitrile, 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.
General procedure: Toa solution of 2-bromobenzyl cyanide (20.0 g, 0.1 mol) in THF (100 mL) was added1M BH3·THF (200 mL, 0.2 mol) dropwise at 0 oCover 30 min and then heated to reflux for 24 h. After quenchedwith MeOH (50 mL) and 6M HCl (50 mL) at 0 oC, the reaction mixturewas heated to reflux for another 4 h and concentrated under reduced pressure.The residue was diluted with H2O (300 mL) and washed with EA (75 mL×2). The aqueous layer was then neutralized by 15% NaOH, extracted with EA (75mL ×2). The combined organic layer was dried over Na2SO4and concentrated under reduced pressure to afford compound 2a as yellow oil (17.4 g, 85.2%).
The synthetic route of 16532-79-9 has been constantly updated, and we look forward to future research findings.
