A convenient synthesis of 4-chloro- and 4-bromocinnolines from o- aminophenylacetylenes

Article abstract of DOI:10.1080/00397919408010177

4-Chlorocinnolines and 4-bromocinnolines have been obtained in fair to good yields by diazotation of o-aminophenylacetylenes with sodium nitrite and concentrated hydrochloric acid or hydrobromic acid at temperatures between 25 and 30°C.
