ChemInform Abstract: Acid and Alkaline Hydrolysis of 2‐Amino‐7‐chloro‐5‐phenyl‐1,3,4‐benzotriazepines.

Abstract Short time acidic hydrolysis of the triazepines (I) yields the hydrazinoquinazolines (II) which are cleaved upon prolonged heating to give the quinazolinones (III) as the main products, together with the benzophenones (IV) and the hydrazines (V).
