N-methyl-methylthio-2-nitroethenarnine is synthesized when MeNO2,CS2,anhydrous EtOH,KOH,CH3NH2,(CH3)2SO4 are used as raw materials and through the condensation-aminoation-methylation in the experiment.In aminoation and methylation progresses,water is used as solvent and substituted traditional organic solvent.Using the new technics not only lower the cost of production,but also eliminate solvent pollution.The overall yield of the produc is 40.5%.
