Paragraph 0018; 0025-0029; 0043-0047; 0061-0065, (2020/02/14)
The invention provides a synthetic method of 4-(difluoromethyl)-2-hydroxypyridine-5-sulfonyl chloride, and belongs to the field of organic chemical synthesis. The synthetic method mainly comprises thefollowing steps: reacting a compound B with diethylamino sulfur trifluoride to obtain a compound C; reacting the compound C with sodium iodide and trimethylchlorosilane to obtain a compound D; reacting the compound D with benzyl mercaptan and 4, 5-diphenylphosphine-9, 9-dimethyl xanthene under the action of an alkali and a catalyst to obtain a compound E; and reacting the compound E with N-chlorosuccinimide to obtain a final product compound F. The method is high in selectivity, mild in reaction condition, simple in synthesis operation and easy to implement. In the synthesis process, the compound B is a self-made synthetic material, 5-bromo-2-methoxypyridine is used as a raw material, and nucleophilic substitution reaction is performed to obtain the compound B.
