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. 57946-63-1, name is 2-Bromo-4-(trifluoromethyl)aniline, A new synthetic method of this compound is introduced below., Recommanded Product: 57946-63-1
General procedure: Under argon condition [26], p-TsCl (p-toluenesulfonyl, 1.2 mmol) in 2 mL dichloromethane was injected to the 2 mL dichloromethane mixture of compounds 1?9 (1 mmol) and 4-dimethylaminopyridine (2.4 mmol) at reflux temperature. The aromatic amine or heteroaromatic amine (1.2 mmol) was injected to the reaction mixture 2 h later. The mixture was stirred for another 2 h. After removing solvent in vacuo, the residue was quenched with EtOAc and water, neutralized with sat. NaHCO3 solvent, the EtOAc layer was dried over anhydrous Na2SO4 and concentrated. The residue was chromatographed on silica gel (EtOAc?petroleum ether) to give target compounds. The structures of compounds 1a-9s were showed in the Supporting information.
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.
