Procedure
To a 100 ml three necked round bottom flask was added N-((6-chloropyridin-3-yl)methyl)ethanamine (17.0 g, 0.1 mol), (2-nitroethene-1,1-diyl)bis(methylsulfane) (15.0 g, 0.09 mol), dry ethanol (50 mL). The mixture was refluxed. After completion, the reaction mixture was cooled to r.t. and concentrated under reduced pressure to obtain crude product as oil, which was purified by column chromatography to afford 5.3 g N-((6-chloropyridin-3-yl)methyl)-N-ethyl-1-(methylthio)-2-nitroethenamine in 18.5% yield.
