In the present study, synthesis of a series of some novel 3-(Quinolin-3-yl)-5,7-dimethyl-1,2,4-triazolo[4,3-a]pyrimidine derivatives (4a–e) has been achieved by oxidative cyclization of new pyrimidinyl hydrazone intermediates (3a–e) using hypervalent iodine reagent(III) under mild conditions. The structures of all synthesized compounds were established on the basis of IR, NMR (1H and 13C), mass spectral...
