Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 14508-49-7, name is 2-Chloropyrazine, A new synthetic method of this compound is introduced below., Computed Properties of C4H3ClN2
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.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
