Some [1,2,4]triazolo[1,5‐ c ]quinazolin‐5(6 H )‐ones 7 , the corresponding isomers [1,2,4]triazolo[4,3‐ c ]quinazo‐lin‐5(6 H )‐ones and the 5‐amino derivatives 8, 9 and 11 have been synthesized starting from the acylamidrazones 5 . The preparation of 5 H ‐[1,2,4]triazolo[1,5‐ d ]‐1,4‐benzodiazepin‐6(7 H )‐ones 15 and of 5‐cyclicaminomethyl‐[1,2,4]triazolo[1,5‐ c ]quinazolines 16 and 17 is also reported.
