our study in the condensed quinazolinone series1, 2), we recently described the synthesis and antihypertensive activity of some 4‐amino[1,2,4]triazolo[4,3‐a]quinazolin‐5(4H)‐one derivatives (1a‐c, R=H, OH, SH). Now, we wish to report the conversion of one of these derivatives, namely 4‐amino‐1‐mercapto‐[1,2,4]‐triazolo[4,3‐a]quinazolin‐5(4H)‐one (1c) into a more complicate condensed quinazolinone system
作为我们在缩合喹唑啉酮系列 1, 2) 中研究的逐步延续,我们最近描述了一些 4-氨基 [1,2,4] 三唑并 [4,3-a] 喹唑啉-5 (4H) 的合成和抗高血压活性-一个衍生物(1a - c,R = H,OH,SH)。现在,我们希望报告这些衍生物之一的转化,即 4-amino-1-mercapto-[1,2,4] -triazolo [4,3-a] quinazolin-5 (4H) -one (1c)进入更复杂的缩合喹唑啉酮系统。
