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. 376646-62-7, name is (4-Bromo-2-methylphenyl)methanamine, A new synthetic method of this compound is introduced below., Formula: C8H10BrN
To a suspension of (4-bromo-2-methyl-phenyl)methanamine (1 .02 g, 5.10 mmol) and DIPEA (2.66 mL, 15.29 mmol) in anhydrous THF (20 mL), cooled at 0 °C under a nitrogen atmosphere, was added 2-methoxybenzoyl chloride (0.83 mL, 5.61 mmol). The reaction mixture was stirred overnight at room temperature, quenched with a saturated aqueous solution of ammonium chloride and then extracted with EtOAc (x3). The combined organics were washed with brine, dried over Na2S04 and filtered then concentrated under reduced pressure. Further purification by flash column chromatography on silica gel eluting with 0-30percent EtOAc in heptane gave /V-[(4-bromo-2-methyl- phenyl)methyl]-2-methoxy-benzamide (0.83 g, 2.49 mmol, 49percent yield) as a white solid. UPLC-MS (ES+, Short acidic): 1 .85 min, m/z 336.1 [M+2]+
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.
