Synthesis of Novel 2-Methylsulfanyl-4<i>H</i>-[1,2,4]triazolo[1,5-<i>a</i>]quinazolin-5-one and Derivatives

Abstract

Abstract A novel 2-methylsulfanyl-4H-[1,2,4]triazolo[1,5-a]quinazolin-5-one was synthesized using dimethyl-n-cyanoimidodithiocarbonate and 2-hydrazinobenzoic acid as building blocks. Chemical transformation of the inherent lactam moiety in the targeted 2-methylsulfanyl-[1,2,4]triazolo[1,5-a]quinazolin-5-one offered access to a variety of derivatives.
