実験手順

To a 10 milliliter solution of 5 Normal sodium hydroxide was added a mixture of 5 grams of tetrachloro-4-hydrazinopyridine in 25 milliliters of isopropanol. The mixture was heated at its boiling point with rapid stirring for 2 hours. The mixture was mixed with 100 milliliters of water and the organic material extracted with methylene chloride. The organic phase was water washed and subjected to sublimation. The 2,5,6-trichloropyridine product was recovered in a yield of 1.85 grams (~ 51 percent of theoretical).
