Halogenoquinoxalines azidolysis

Preparation. All recently used routes to azidoquinoxalines have been covered already by azidolysis of halogenoquinoxalines (Sections 3.2.4 and 3.4.5), by azidolysis of alkylsulfonylquinoxalines (Section 5.4), by diazotization and subsequent azidolysis of quinoxalinamines (Section 6.3.2.3), and by treatment of hydrazinoquinoxalines with nitrous acid (Section 6.4.2.1).
