Keywords:
N-aryl-6-azido-1H-pyrazolo[3, 4-b]pyridine-5-carbaldimines, 6-aryl-1, 6-dihydrodipyrazolo-[3, 4-b, 4, 3-e]pyridines, thermolysisAbstract
6-Azido-1H-pyrazolo[3,4-b]pyridino-5-carbaldehydes react with aromatic amines to give the corresponding N-arylimines which cyclize on heating in boiling toluene to give 6-aryl-1,6-dihydrodipyrazolo[3,4-b:4,3-e]pyridines.
