Synthetic Route of 623-00-7, These common heterocyclic compound, 623-00-7, name is 4-Bromobenzonitrile, 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: A mixture of aryl silane (0.5 mmol), aryl bromides (0.5 mmol), PdCl2(MeCN)2 (5 mol%), and CsF (0.5 mmol) was stirred at 100oC for 6 h in NMP under CO (1atm) (5 mL). Afterwards, 2 mL water was added to the reaction solution and then filtered through a filter paper and the solution was extracted by Et2O (2 mL) for three times. The organic phase was combined and evaporated under reduced pressure. The residue was purified on a SiO2 column to afford the desired product(ethyl acetate/hexane).
The synthetic route of 623-00-7 has been constantly updated, and we look forward to future research findings.
