Adding a certain compound to certain chemical reactions, such as: 54962-75-3, name is 3-Bromo-5-(trifluoromethyl)aniline, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 54962-75-3, Formula: C7H5BrF3N
Add propylene oxide (36 mg, 0.624 mmol) and lithium perchlorate (56 mg, 0.458 mmol) to the solution of 3-bromo-5-(trifluoromethyl)aniline (100 mg, 0.416 mmol) in acetonitrile (5 mL), stir the resulting mixture overnight at ambient temperature. Upon completion of the reaction, concentrate the mixture under reduced pressure. Purify the residue by flash chromatography (silica gel, PE_EtOAc=5:l) to afford the product (136 mg, 100%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Bromo-5-(trifluoromethyl)aniline, and friends who are interested can also refer to it.
