Reaction Steps

A mixture of 2-[[[5-(methylamino)methyl-2-furanyl]methyl]thio]ethanamine (0.9 g) and N-methyl-1-methylthio-2-nitro-etheneamine was heated at 100°-120° for 30 mins under water pump pressure. The residue was purified by column chromatography (silica/methanol:0.88 ammonia) to give N-[2-[[[5-(methylamino)methyl-2-furanyl]methyl]thio]ethyl]-N'-methyl-2-nitro-1,1-ethenediamine which was crystallised from acetonitrile m.p. 106°-108° (0.65 g).
