| Abstract: | The Vilsmeier Haack heterocyclization of 2‐aryl amino‐4‐phenyl quinolines quinoline yielded the hitherto unknown 5‐phenyl‐dibenzo[b,g][1,8]naphthyridines in quantitative yield. The synthesis of aryl amines was achieved by the action of anilines on 2‐chloro‐4‐phenyl quinoline, which in turn was sourced through the combes reaction of benzoyl acetanilides. |
