실험 절차

A solution of 5.39 gm (0.02 mole) of 2,4,5-trichlorophenoxyacetic acid hydrazide, 2.42 gm (0.02 mole) of 4-acetylpyridine, 125 ml of dioxane and 2 ml of acetic acid is refluxed 4 hr. The hot solution is filtered. The filtrate is diluted with water until cloud point. The mixture is cooled to room temperature and then chilled in the refrigerator. The product is collected to yield 6.24 gm (83%) of the title compound having a melting point of 227.4° C. (decomp).
