| Abstract: | A novel series of 2‐alkoxy(aralkoxy)‐4H‐[1,2,4]triazolo[1,5‐a]quinazolines were synthesized employing N‐cyanoimidocarbonates and 2‐hydrazinobenzoic acid as building blocks. Chemical transformation of the inherent lactam moiety in the targeted 2‐alkoxy(aralkoxy)[1,2,4]triazolo[1,5‐a]quinazolines was offered access to a variety of derivatives. J.
