An efficient, simple, and practical method of preparation of nitro phenols and chloropyridinols has been reported by the active chlorine displacement of chloro nitro benzenes and poly chloro pyridines in the presence of alkali metal hydroxide in low polarity solvent with very good yields.

Sterically non-demanding Grignard and organolithiumreagents displace the methoxy-group in tetrachloro-4-methoxy-pyridine, with the formation of 4-alkyl- or 4-aryl-tetrachloropyridines. t-Butyl-lithium forms trichloro-4-methoxy-3-pyridyl-lithium, which decomposes in the presence of furan with the formation of 2,3-dichloro-5,8-dihydro-4-methoxy-5,8-epoxyquinoline.

chloropyridines depending on the reaction conditions. Substitution on 2,4,6-tris(4-dimethylamino)pyridinium-substituted 3,5-dichloropyridine gave the corresponding 2,4,6-tris-alkoxy- or -phenoxy-substituted pyridines which are not available by other routes.
