Abstract

Synthesis of a series of triazolopyrimidines (4a-j) was achieved from different acetoacetamides, thiophene-2- carbaldehyde and 5-amino-1,2,4-triazole using microwave irradiation within 20-30 minutes with high yield. The structures of the products were supported by FTIR, PMR and mass spectral data.
