2-Chloro-3-nitro-6-methylpyridine Use and Manufacturing
Synthesis of the compound 26 The compound 25 (10g, 0.065 mol) was added into 50 mL of phosphorus oxychloride and heated under reflux for 4 h, then was subject to a distillation under a reduced pressure to remove most of phosphorus oxychloride, and the remaining part was poured into 200 g of ice-water, followed by agitation for 2h. A large amount of the precipitate was precipitated, filtrated under a reduced pressure, and vacuum-dried to obtain 10 g of a white product with a yield of 89percent. The melting point is 68.5-70.5°C (water) [J.O.C. , 1955, 20, 1729-1731].When in accordance with the procedure of example 1, equal molar amounts of the following are substituted for 3-nitro-2-chloropyridine: 2-chloro-3-nitro-4-methylpyridine, 2-chloro-3-nitro-5-methylpyridine, 2-chloro-3-nitro-6-methylpyridine, 2-chloro-3-nitro-5, 6-dimethylpyridine, 2-chloro-3-nitro-6-methoxypyridine, and 4-chloro-3-nitro-2-methylpyridine,
