Abstract
Three component condensation of 3-amino-1,2,4-triazole with an aromatic aldehyde and ketone gives 1,2,4-triazolo[1,5-a]-pyrimidines. An x-ray structural investigation of 5-phenyl-4,5,6,7-tetrahydro-1,2,4-triazolo[1,5-a]benzo[h]quinazoline was undertaken in order to determine the course of this reaction.
