Paragraph 0024-0026; 0035-0037; 0046-0048, (2020/01/03)
The invention relates to a chemical synthesis method of thiazolo[4,5-b]pyridyl-6-carboxylic acid. According to the method, starting from 3,5-dibromo-2-aminopyridine as a raw material, five steps of reactions comprising an acylation reaction, a cyclization reaction, a diazotization reaction, a carbonyl insertion reaction and a hydrolysis reaction are carried out to synthesize the thiazolo[4,5-b]pyridyl-6-carboxylic acid. An efficient synthesis method is provided for synthesis of the compound.
