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. 16532-79-9, name is 4-Bromophenylacetonitrile, A new synthetic method of this compound is introduced below., Application In Synthesis of 4-Bromophenylacetonitrile
To a solution of 2-(4-bromophenyl)acetonitrile (2.00 g, 10.20 mmo) in THF (20 mL) was added NaH (1.22 g, 30.60 mmol, 60% purity) at 0 C. The mixture was stirred at 0 C for 30 mins, then Mel (4.34 g, 30.60 mmol, 1.90 mL, 3.00 eq) was added to the mixture. The mixture was stirred at 15 C for 16 hours. The mixture was quenched with sat.NH4Cl (50 mL) and extracted with EtOAc (50 mL x 2). The combined organic phase was washed with brine (20 mL), dried over Na2S04, filtered and concentrated to give the crude product that was purified by flash chromatography on silica gel (PE: EtOAc = 20:1 to 10:1) to afford A-73 (400.00 mg) as an oil. H NMR (400MHz, CDC13) _ = 7.53 (d, 2H), 7.36 (d, 2H), 1.72 (s, 6H).
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.
