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. 4457-67-4, name is 1-Bromo-4-methoxybutane, A new synthetic method of this compound is introduced below., Safety of 1-Bromo-4-methoxybutane
A solution of 4-methoxybutyl bromide (4.5 g) in acetonitrile (15 ml) is added dropwise under reflux to a mixture of salicylic acid ethyl ester (2.63 ml), powdered potassium carbonate (3.10 [G)] and potassium iodide (10 mg) in acetonitrile (50 ml), and the reaction mixture is then stirred overnight. After cooling, filtration is carried out, the filtrate is concentrated and the residue is added under a high vacuum. The title compound (4.4 g), Rf (C) =0.28, is obtained in the form of a pale-yellow oil.
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.
