Versuchsvorschrift

To a solution of 3-chloro-6-pyridin-2-ylpyridazine (0.250 g, 1.300 mmol) in acetonitrile (15 mL) was added piperazine (0.335 g, 3.900 mmol) and the mixture was stirred at reflux for 4 hours. The solvent was removed in vacuo. The residue was purified by column chromatography to afford the title compound in 77% yield (0.240 g).
