Versuchsvorschrift

A mixture of 4-(5-bromo-3-methylpyrid-2-yl)butylamine (11.79 g) and 2-chloro-3-nitro-5-(pyrid-3-ylmethyl)-pyridine hydrochloride (4.57 g) was refluxed in ethanol (100 ml) for 8 hours. The solvent was removed in vacuo, the residue was dissolved in water (100 ml) and then extracted with chloroform (100 ml). The chloroform extract was chromatographed on silica eluted with 5% v/v methanol in chloroform followed by recrystallisation from chloroform/hexane to give the title compound as a yellow solid, m.p. 82°-84° C.
