Abstract

The condensation of 5-(2-hydroxyphenyl)-6, 7-dihydro-1, 2, 4-triazolo[l, 5-a]pyrimidines with aldehydes yields derivatives of a new heterocyclic system, namely, 3,7-dihydro-2H-1,2,4-triazolo[1′,5′-a′]pyrimido[4,5-d]-benzo[b]pyran, including the 9-methyl-2,3-diphenyl derivative, whose structure was established by x-ray diffraction structural analysis.
