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. 109-08-0, name is 2-Methylpyrazine, A new synthetic method of this compound is introduced below., SDS of cas: 109-08-0
General procedure: A 25 mL Schlenk tube equipped with a magneticstirring bar was charged with2,6-lutidine (0.75 mmol, 3equiv.), p-nitro-benzaldehyde(0.25 mmol), dioxane/water(1:1, 1ml) and [Hmim][H2PO4](1equiv.).The tube was sealed and heated at 100 for 24h. Aftercompletion of the reaction, the resulting solution was extracted with ether (3×10 ml). The organic layer was dried with anhydrous Na2SO4,and concentrated under vacuum. The residue was chromatographed on a silica gelcolumn eluted with a mixture of petroleum ether and ethyl acetate (1:1) to givepure products (92percent).
The synthetic route of 109-08-0 has been constantly updated, and we look forward to future research findings.
