Procedure

To a reaction vessel containing 10 milliliters of dioxane was added ~0.5 gram (~0.002 mole) of tetrachloro-4-hydrazinopyridine. To this mixture was added portionwise 10 milliliters of a 5.25 percent sodium hypochlorite solution (0.07 mole). The mixture was held until the dark color cleared and was poured over ice. The solid 2,3,5,6-tetrachloropyridine was recovered by filtration and found to be pure by infrared and vapor phase chromatographic analyses.
