Procedure

To a reaction vessel containing 200 milliliters (0.14 mole) of 5.25 percent sodium hypochlorite was added 10 grams (0.04 mole) of 2,3,5,6-tetrachloro-4-hydrazinopyridine. The mixture was heated at the boiling point for 1 hour, cooled and the solid which precipitated was recovered by filtration and dried. The 2,3,5,6-tetrachloropyridine was recovered in a yield of 7.0 grams (84 percent of theoretical) and the structure of the product was confirmed by infrared analysis and vapor phase chromatography.
