Reaction Steps

A mixture of 5.2 g of 2-(N-n-butyl-N-methylamino)-2-methylthio-1-nitroethylene, 2.84 g of pyridin-3-ylmethylamine and 3.69 g of disodium hydrogen phosphate in 30 ml of ethanol is refluxed for 1 hour. After removing the salt by filtration, the solvent is evaporated from the solution under vacuum and the residue is chromatographed through a column of silica gel with a 95/5 mixture of ethyl acetate/methanol. The product is eluated with ethylacetate/methanol (85/15). The solvent is removed by evaporation, affording 3.7 g of 2-(N-n-butyl-N-methylamino)-2-(pyridin-3-ylmethylamino)-1-nitroethylene as a viscous oil (Compound 3.2, Table 3).
