Improved synthesis of 2-amino-1,2,4-triazolo[1,5-a]pyrimidines

An improved procedure is suggested for preparing 2-amino-1,2,4-triazolo[1, 5-a]pyrimidines from 3,5-diamino-1,2,4-triazole and unsaturated aromatic ketones, with acetyl protection of the amino group in the step of oxidation of 2-amino-4,7-dihydro-1,2,4-tr

CYCLOCONDENSATION OF CHALCONES WITH DI- AND TRIAMINO-1,2,4-TRIAZOLES

We have carried out the synthesis of 2-amino-5,7-diaryl-1,2,4-triazolopyrimidines from chalcones and 3,4,5-triamino-1,2,4-triazole and synthesized them independently via the 4,7-dihydro derivatives.The course and mechanism of the cyclocondensation
