Reaction of N-arylamides of acetoacetic acid with aromatic aldehyde and 3-amino-1,2,4-triazole derivatives has resulted in N,7-diaryl-5-methyl-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidine-6-carboxamides.
Multicomponent Facile Synthesis of Highly Substituted [1,2,4]Triazolo[1,5-<i>a</i>] Pyrimidines
A simple and convenient method for one-pot synthesis of a series of potentially biologically active [1,2,4]triazolo[1,5-a]pyrimidine-6-carboxamide derivatives has been developed in solvent-free conditions using maltose as a commercially available, cheap and eco-friendly catalyst. The salient features of the present protocol are mild reaction conditions, good to excellent yields, high atom economy,
