摘要
The synthesis and characterization of several 3‐aryl‐1,2,4‐triazolo[4,3‐c]quinazolines is described. The first step comprises the condensation of aromatic aldehydes with 2‐(H or Cl)‐4‐hydrazinoquinazolines 2 to afford the corresponding hydrazones 3. The second step involves the cyclization to the title compounds 4 in bromine/acetic acid. Reaction of 4 (X = Cl) with cyclic amines gave the corresponding 5‐cyclicamino 5 or 5‐alkoxy derivatives 6.
