Reaktionsschritte

A mixture of 4-(4-dimethylaminomethyl-2-pyridyl)butylamine (1 g) and 2-nitroamino-5-(6-methyl-3-pyridylmethyl)-4-pyrimidone (1.26 g) in pyridine (5 ml) was refluxed for 4.5 hours. The solvent was removed in vacuo, the residue chromatographed and then crystallised from ethanol:ether (1:10) to yield 2-[4-(4-dimethylaminomethyl-2-pyridyl)butylamino]-5-(6-methyl-3-pyridylmethyl)-4-pyrimidone (0.86 g) m.p. 135°-137°.
