실험 절차

A mixture of 6.81 gm (0.05 mole) of benzhydrazide, 6.06 gm (0.05 mole) of 2-acetylpyridine and 100 ml of ethanol is stirred at reflux 2 hr. Then sufficient dioxane is added to the boiling mixture to furnish a solution. The hot solution is filtered. The filtrate is diluted to the cloud point with water, cooled to room temperature, and then chilled in the refrigerator. The product is collected and dried to yield 7.61 gm (64%) of the title compound having a melting point of 151.6° C.
