NYLMETHYL-5-METHYL-1,2,4-TRIAZOLO[1,5-A]PYRIMIDINE

The crystal structure of the title ester, ethyl -methyl-1,2,4-triazolo [1,5-a]pyrimidine-7-acetate, C10H12N4O2, is described. In the field of heterocyclic chemistry, the prospects offered for the design of antiv iral agents, as well as the chemistry of interaction of N-bridged puri ne analogue ligands with heavy metals, are of biological and environme ntal importance. This study has elucidated the isomeric structure of a heterocyclic product of the condensation of 3-amino-1,2,4-triazole an d 4-hydroxy-6-methyl-2H-pyran-2-one (triacetic acid lactone).
