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. 653-92-9, name is Methyl 2-bromo-4-fluorobenzoate, A new synthetic method of this compound is introduced below., Safety of Methyl 2-bromo-4-fluorobenzoate
EXAMPLE 18AMETHYL 4-FLUORO-2-PHENETHYLBENZOATEMethyl 2-bromo-4-fluorobenzoate (1.00 g), (E)-styrylboronic acid (0.89 g), tetrakis(triphenylphosphine)palladium(0) (0.50 g), and K3PO4 (2.28 g) were stirred in dioxane (17 mL) at 90 C. for 24 hours. The reaction mixture was chromatographed on silica gel with 1-5% ethyl acetate/hexanes. The product in methanol (10 ml) was added to 20 wt % of fresh dry 5% Pd-C and stirred 4 days with H2 in a pressure bottle. The mixture was filtered through a nylon membrane and concentrated.
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.
