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. 1223434-15-8, name is Methyl 4-bromo-2-cyanobenzoate, A new synthetic method of this compound is introduced below., Recommanded Product: Methyl 4-bromo-2-cyanobenzoate
A mixture of Compound II (980 mg), 2N aqueous lithium hydroxide solution (6.1 mL) and methanol (18 mL) was stirred at room temperature for 4 hours. The reaction mixture was concentrated under reduced pressure, and to the residue was added 1N aqueous sodium hydroxide solution, and the mixture was extracted with ethyl acetate. The aqueous layer was acidified with 4N hydrochloric acid, and then extracted with chloroform. The chloroform layer was dried over sodium sulfate, and then concentrated under reduced pressure to give Compound III (808 mg).
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.
