2-Aminoquinolines 4 were obtained in an one-pot reaction from arylacetaldehydes 1, secondary amines 2 and aryl azides 3 in refluxing benzene or xylene. 2,4-Diaminoquinolines and 2,4-diamino-l,7-naphthyridines 9 were prepared by heating arylacetaldehydes 1 with secondary amines 2 and aryl or pyridyl azides 8 and reaction with bases. Reaction intermediates were shown in certain cases to be 5-amino-ν-triazolines
