Procedure

A mixture of 6.76 gm (0.05 mole) of 3-propionylpyridine, 6.81 gm (0.05 mole) of benzhydrazide and 100 ml of absolute ethanol is refluxed 8.5 hr. The hot solution is filtered. The filtrate is cooled to room temperature and then chilled. The crystals that separate are collected and dried to yield 10.18 gm (80%) of the title compound having a melting point of 169.4° C.
