In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 14862-52-3 as follows. Recommanded Product: 14862-52-3
General procedure: A mixture of 1,3-dibromo-5-chlorobenzene (2 g, 7.41 mmol), 9Hcarbazole(2.60 g, 15.56 mmol), tris(dibenzylideneacetone)dipalladium(339 mg, 0.37 mmol), 2-dicyclohexylphosphino-2?,6?-dimethoxy-1,1?-biphenyl (457 mg, 1.11 mmol) and sodium tert-butoxide (2.85 g,29.64 mmol) in 100 ml of toluene were heated at 80 C for 4 h underargon. After cooling down to room temperature, the mixture was extractedwith dichloromethane. The combined organic extracts weredried over Na2SO4 and evaporated under reduced pressure. The crudeproduct was purified by column chromatography on silica gel usingpetroleum ether/dichloromethane (PE/DCM, 8/1, v/v) as the eluent toafford the target compound (2.46 g, 75%).
According to the analysis of related databases, 14862-52-3, the application of this compound in the production field has become more and more popular.
