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. 5445-17-0, name is Methyl 2-bromopropanoate, A new synthetic method of this compound is introduced below., SDS of cas: 5445-17-0
After dissolving 5 g (19.06 mmol) of triphenylphosphine in 15 ml of toluene, an aqueous solution of 0.32 g (1.90 mmol) of potassium iodide in 15 ml of distilled water and 3.2 ml (28.6 mmol) of methyl 2-bromopropionate were added thereto. And the mixture was stirred at 70 C for 20 hours. After completion of the reaction, the reaction mixture was cooled to room temperature, basified (pH 9) with 10 N aqueous sodium hydroxide solution, and extracted with dichloromethane. The obtained organic layer was dried over anhydrous sodium sulfate, filtered under reduced pressure, and distilled under reduced pressure. The obtained solid was washed with hexane and then filtered under reduced pressure and dried under reduced pressure to give 6.0 g (yield: 91%) of the title compound.
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.
