Abstract
The structures of substituted 6-benzyloxycarbonyl-7-(het)aryl-5-methyl-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidines and isomeric 6-benzyloxycarbonyl-7-aryl-5-methyl-4,7-dihydro-1,2,4-triazolo[4,3-a]pyrimidines were studied by X-ray diffraction. Distinctive structural features of these compounds were revealed.
