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
描述了几种3-芳基-1,2,4-三唑并[4,3-c]喹唑啉的合成和表征。第一步包括将芳族醛与2-(H或Cl)-4-肼基喹唑啉2缩合,得到相应的hydr 3。第二步涉及在溴/乙酸中环化成标题化合物4。的反应4与环状胺(X =氯),得到相应的5- cyclicamino 5或5-烷氧基衍生物6。
