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. 55666-43-8, name is tert-Butyl 3-bromopropanoate, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H13BrO2
To a stirred mixture of 3-[(methylamino)methyl]benzonitrile (6.1 g, 41.7 mmol) and sodium bicarbonate (7.0 g, 83.4 mmol) in ACN (70 mL) was added dropwise tert-butyl 3-bromo- propanoate (7 mL, 41.7 mol). After being stirred at RT for 12 hours, the reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was purified by chromatography (silica, pet ether/EtOAc) to afford the title compound as a pale yellow liquid. 1H NMR (DMSOd6, 400 MHz) delta 7.70 (s, 2H), 7.60 (m, 1 H), 7.51 (m, 1 H), 3.49 (s, 2H), 2.58 (m, 2H), 2.36 (m, 2H), 2.09 (s, 3H), 1.38 (s, 9H).
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.
