Procedure
2.2 g of 2-pyridinecarbaldehyde was added to a mixture of 3.6 g of p-chlorophenylhydrazine hydrochloride and 9.8 g of sodium acetate in 60 ml of 50% by volume aqueous ethyl alcohol. The mixture was refluxed for 10 minutes, cooled and the precipitate crystallized from ethyl alcohol to give 2, as yellow crystals, mp 184°-186° C.
