Nucleophilic displacement of aromatic fluorine, Part II Indazoles, indazolo[2,3‐c]quinazolines, indazolo[2,3‐d] [1,4]benzodiazepines and indazolo[2,3‐c]benzo‐1,2,3‐triazenes

Abstract 3‐(2‐Arninophenyl)indazoles 2 were prepared by the reaction of the o ‐fluorobenzophenones 1 with hydrazines. These indazoles were converted to the tetracyclic title compounds by conventional methods.
