Azidolysis of Nuclear Halogenoquinoxalines

Provided they occupy the 2- or 3-position in regular quinoxalines or the 2-, 3-, 6-, or 7-position in 5,8-quinoxalinequinones, halogeno substituents are easily [Pg.164]

2-Chloro- (172, R = Cl) gave 2-azido-3-ethoxycarbonylmethylquinoxaline (172, R = N3) (NaNs, HCl, H20-Et0H, reflux, 4h 80%) homologs likewise. [Pg.165]

6-Dichloro-l-methyl-2(lf/)-quinoxalinone (173, R = C1) gave 3-azido-6-chloro-l-methyl-2(l//)-quinoxalinone (173, R = N3) (NaNs, Mc2NCHO, 120°C, 90 min 96%) analogs Ukewise. [Pg.165]
