Without the use of catalysts and oxidants, a facile and sustainable electrochemical bromination protocol was developed. By introducing the directing groups, the regioselectivity of pyridine derivatives could be controlled at themeta-position utilizing the inexpensive and safe bromine salts at room temperature. A variety of brominated pyridine derivatives were obtained in 28-95% yields, and the reaction could be readily performed at a gram scale. By combining the installation and removing the directing group, the concept ofmeta-bromination of pyridines could be verified.

Paragraph 0007; 0020; 0022; 0026; 0028; 0032; 0034, (2021/02/06)
The invention discloses a method for synthesizing 2-amino-3-chloro-5-trifluoromethylpyridine, and belongs to the technical field of organic synthesis. Specifically, starting from 2-aminopyridine, three chemical reactions of bromination, chlorination and coupling are involved, and two organic solvents are used in the whole process; and after the three-step reaction, recrystallization treatment is carried out to obtain the high-purity 2-amino-3-chloro-5-trifluoromethylpyridine. The method is mild in reaction condition and easy to control, and the obtained product is high in purity; reaction rawmaterials and organic solvents are easy to obtain and low in price, and a new way is provided for large-scale production.
