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. 20781-20-8, name is (2,4-Dimethoxyphenyl)methanamine, A new synthetic method of this compound is introduced below., HPLC of Formula: C9H13NO2
Into a vial was added the 4-bromo-2-fluoro-N-thiazol-2-yl-benzenesulfonamide (2.60 g, 0.00771 mol), sodium tert-butoxide (1.78 g, 0.0185 mol), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (0.27 g, 0.00046 mol), tris(dibenzylideneacetone)dipalladium(0) (0.14 g, 0.00015 mol) and 1,4-dioxane (24.1 mL, 0.308 mol). Argon was bubbled for 15 minutes. 2,4-Dimethoxybenzylamine (1.40 mL, 0.00925 mol) was added and the reaction mixture was heated at 100 C. overnight. The reaction mixture was cooled to room temperature then filtered over Celite. The filtrate was concentrated to give the crude product that was purified via automated flash chromatography (silica gel, 50% EtOAc in hexanes to 100% EtOAc) to give the product as a yellow solid (2.59 g, 79.3%)
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.
