A solution of 2-[[[5-(methylamino)methyl-2-furanyl]methyl]thio]ethanamine (10 g, 0.05 mole) and N-methyl-1-methylthio-2-nitroetheneamine (7.4 g) in water (25 ml) was stirred at 50° for 2 hr. Acetone (350 ml) was added and the solvent was removed by distillation at atmospheric pressure until 275 ml of distillate had been collected. Ethanolic hydrogen chloride (2M; 27.5 ml) was added to the residue and the solution was stirred overnight at room temperature. The product (11.0 g) m.p. 161°, was collected and recrystallised from ethanol as a colourless microcrystalline solid (10.1 g) m.p. 162°. Analysis Found: C, 42.6; H, 6.3; N, 16.4. C12H20N4O3S.HCl requires: C, 42.8; H, 6.2; N, 16.6%.
