Synthesis, spectroscopic characterization, thermal, XRD crystal structure, the PLATON structural analysis, and theoretical studies of a new 1,2,4-triazolo-[1,5-a]pyrimidines derivatives

The current work reports the synthesis of two new triazolopyrimidine derivatives from 3-aminotriazole and ethyl 3-phenylglycidate. The two new compounds were characterized using IR spectra, UV–vis spectra, NMR ( 1 H and 13 C), thermal analyses (TGA and DTA) and finally the structure of one was confirmed by X-ray diffraction studies. Quantum chemical calculations were also conducted to corroborate experimental findings. © 2019 Elsevier B.V.
