Procedure

A solution of 2-(5-methyl-4-imidazolylmethylthio)ethylamine (0.51 g, 0.003 mol) and 2-methylthio-3-nitro-1,4,5,6-tetrahydropyridine (0.49 g, 0.003 mol) in ethanol (50 ml) was refluxed for 6 hours. The mixture was cooled, and the solvent was removed in vacuo. The residue was dissolved in hot propan-2-ol and the product crystallised on cooling. Recrystallisation of the product from propan-2-ol/methanol gave 2-[2-(5-methyl-4-imidazolylmethylthio)ethylamino]-3-nitro-1,4,5,6-tetrahydropyridine (0.66 g, 82%) m.p. 205.5°-206.5°.
