| titleOfInvention | A kind of method for synthesizing 2-halogenated-3-substituted hydrocarbyl sulfonyl pyridine and intermediate thereof by microwave method |
| abstract | The invention discloses a method for synthesizing 2-halogenated-3-substituted hydrocarbyl sulfonyl pyridine and an intermediate thereof by a microwave method. A reactor is charged with substituted amino acrolein, a catalyst and a substituted cyanoethyl sulfone, and under microwave irradiation Reaction, follow the reaction to complete reaction of substituted amino acrolein or substituted cyanoethyl sulfone to obtain an intermediate; then add hydrogen halide to the reaction solution to continue the reaction, track and detect until the reaction is complete; add lye to the reaction solution to adjust the pH value To 7-8, stand for layering to obtain an aqueous layer and an organic layer, the aqueous layer is extracted with an organic solvent, then the organic layers are combined, and then purified to obtain a 2-halogenated-3-substituted hydrocarbylsulfonylpyridine. The method for synthesizing 2-halogenated-3-substituted hydrocarbyl sulfonyl pyridine according to the present invention has the advantages of environmental protection, simple reaction time and simple operation, high product yield and good bactericidal activity of the product. |
