2-Chloro-3-nitropyridine → HCID 131710724, compound

Participants

Reaction Steps

Thus, for example, a compound of the formula ##STR16## is obtained by reaction of 2-chloro-3-nitro-pyridine with 3-diethylaminothiophenol to give 2(3'-diethylaminothiophenoxy)-3-nitro-pyridine, reduction to the 3-amino compound, diazotisation and intramolecular coupling. The oxadiazepine derivative ##STR17## is obtained, for example, by reaction of 3-chloro-4-nitroanisole with 1-diethylamino-3-hydroxynaphthalene to give 1-diethylamino-3-(5'-methoxy-2'-nitro-phenoxy)-naphthalene, reduction to the 2'-amino compound, diazotisation and internal coupling.
