Procedure
2-[[[5-(Dimethylamino)methyl-2-furanyl]methyl]thio]ethanamine (4.25 g) and 1,1-bis(methylthio)-2-nitroethene (3.3 g) were refluxed in acetonitrile (50 ml) for 14 hr. Solvent was removed and the residue dissolved in 36% methanolic methylamine (50 ml) and the solution refluxed for 8 hr. Solvents were removed and the residue in methanol treated with charcoal. Filtration and evaporation of the solvent gave the title compound as Example 15 (5.0 g).
