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 14508-49-7 as follows. Safety of 2-Chloropyrazine
General procedure: A 10 mL round-bottom flask was charged with the prescribedamount of catalyst Pd/Cu, aryl chlorides (0.5 mmol), phenylboronicacids containing hydroxymethyl (0.75 mmol), Cs2CO3 (1.0 mmol)and dioxane (5 mL) in air. The reaction mixture was then placedin an oil bath and heated at 110 C for 24 h. After removal of thesolvent, the resulting residue was purified by flash chromatographyon silica gel using CH2Cl2 as eluent. The products 4a-k, and4m are known compounds [6,9] except for 4l and 4n.
According to the analysis of related databases, 14508-49-7, the application of this compound in the production field has become more and more popular.
