Versuchsvorschrift

A mixture of 2.5 g of 2'-chloro-2,3'-bipyridine, 12.6 ml of anhydrous hydrazine and 50 ml of pyridine was refluxed for 36 hours and concentrated under vacuum to a gum. The gum was dissolved in methylene chloride, treated with activated carbon, dried over sodium sulfate and the solvent removed. The residue was crystallized from etherhexane to give 2.1 g of 2'-hydrazino-2,3'-bipyridine as yellow crystals, mp 64°-65° C.
