, (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.
