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. 3196-15-4, name is Methyl 2-bromobutyrate, A new synthetic method of this compound is introduced below., Recommanded Product: Methyl 2-bromobutyrate
Double-benzyl-isoquinoline (Formula in, X = Br) 6.85g, 2- bromo-7-bromo-butyrate weighed 4.50g wasdissolved in N, N- dimethyl Formamide 100mL, 500mL three-neck flask was added, mixed by stirring, cooled to-10 C, and the reaction was stirred 24h incubation After filtration, filtrate was washed with a small amount of5% hydrobromic acid and, the solvent was distilled off under reduced pressure to a volume of the liquid reducedto 1/4, crystallization at room temperature 8h, Filtered and the filtrate evaporated under reduced pressure to 50%of water, cooled to 5 C to crystallize overnight, filtered and the solid was dried at 60 C 4h, to give the lightThe product 5.20g yellow powder in a yield of 70.29%, a purity of 96.47% (HPLC).
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.
