Indolo[2,1-c]benzo[1,2,4]triazine, a new ring system, was synthesized by diazotization of 2-amino-1 aryltetrahydroindoles followed by an intramolecular coupling of the diazonium group with the aryl moiety. All the new compounds were screened at the NCI for antiproliferative property but none of them showed significant activity.
