Synthesis and properties of azido derivatives of 2- and 4-arylamino-5-cyanochloropyridines

Abstract

Reaction of 2- and 4-arylaminotrichloro-5-cyanopyridines with sodium azide gives 6-azido-2-arylamino-3,4-dichloro-5-cyanopyridines and 2,6-diazido-4-arylamino-3-chloro-5-cyanopyridines respectively. It is shown that the azide group of the monoazidopyridines synthesized, readily undergoes cycloaddition with norbornene, whereas the azide groups of the diazidopyridines are unreactive towards this dipolarophile.
