3-CHLORO-2-METHYLPYRIDINE Use and Manufacturing
54g 3-amino-2-methylpyridine was added to 130g of concentrated hydrochloric acid (mass fraction 36-38percent).Then pass hydrogen chloride to saturation, and add 222.45g of phosphorus oxychloride and 90g of nitric acid of 70percent mass concentration at a temperature of 20-25°C. Stir the reaction and control the reaction.57.3 g of 3-chloro-2-methylpyridine was isolated (yield 89percent, purity 99percent).
