Paragraph 0018-0025, (2021/08/07)
The invention relates to a preparation method of 2-thioether-N, N-dimethyl nicotinamide. The preparation method comprises the following steps: adding 2-chloro-N, N-dimethyl nicotinamide and sodium thiosulfate pentahydrate into an organic solvent at a certain temperature, and carrying out condensation substitution reaction on substituent-containing alcohol by a one-pot method to obtain the product 2-thioether-N, N-dimethyl nicotinamide. The method provided by the invention has the advantages of many raw material sources, obvious cost advantage, safer and more convenient preparation method, high total yield and less three wastes, especially no emission of toxic gases such as ammonia gas or hydrogen sulfide, and is beneficial to industrialization.
