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. 192436-83-2, name is 4-Bromo-N-methoxy-N-methylbenzamide, A new synthetic method of this compound is introduced below., Safety of 4-Bromo-N-methoxy-N-methylbenzamide
To a solution of ibromo-.3.trifluoromethyl)benzene (800 mg, 3.56 mmol) in 1() mL of THF was added Mg (129.6 rng, 5.33 mmoi) under nitrogen protection and stirred at 80CC for 2 h. Then the mixture was added to a solution of 4-hromoN-methoxy-Nmethylhenzamide (433.9 mg, 1.78 mmol) in THF (6mL) at 0 C under nitrogen protection and stirred at 20 C for 12 h. The mixture was poured into aq.N1-14C1 (150 mL) and extracted with ethyl acetate (120 mLx3).The organic layer was dried over Na2 SO4 and concentracted in vacuo to give the residue, which was purified with pre HP LC to give (4-bromophenyl)(3.-(trifiuorornethyi)phenyi)methanone. 1HNMR (400MHz, CDC13): oe = 8.04 (s, IH), 7.95 (d, J=7.8 Hz, IH), 7.87 (d, J=.() Hz, 1H),7.67 (s, 4H), 7.66 7.62 (m, il-i) ppm.
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.
