A novel [1,2,4]triazolo[4,3-c]pyrimidine-8-carboxamide libraries were synthesized via oxidative cyclization of hydrazono-1,6-dihydropyrimidine-5-carboxamide intermediates by the application of Iodobenzenediacetate as a sole cyclizating agent. Here, we report one pot sequential strategy to generate corresponding triazolopyrimidines by condensation of preprepared -acylketene dithioacetals and arylamidines. Moreover, this process describes the application of presynthesized arylamidines which omits the transition metal catalyzed Suzuki-Miyaura cross coupling reaction hence signify the atom- and st...
