Abstract
1) By treating 2-amino-6-methylpyridine with sulfuric and nitric acids, 2-amino-3-nitro- and 2-amino-5-nitro-6-methylpyridines were obtained, with a by-product of 2-hydroxy-5-nitro-6-methylpyridine.
2) 2-Amino-5-nitro-6-methylpyridine was diazotized to 2-hydroxy-5-nitro-6-methylpyridine which was chlorinated with phosphoryl chloride and phosphorus pentachloride to 2-chloro-5-nitro-6-methylpyridine.
3) By the application of the potassium salts of phenols to 2-chloro-5-nitro-6-methyl pyridine, phenyl pyridyl ethers containing nitro group were prepared, the reduction of ethers yielding corresponding amino compounds.
