AbstractCopper-catalyzed Alkyne-Azide Cycloaddition (CuAAC) click chemistry robustness has been demonstrated over recent years to produce 1,2,3-triazoles with excellent yields at mild conditions with simple purification methods. However, the consequences of having copper paramagnetic traces in final products, which complicate spectroscopic assignments and can produce inaccurate conclusions, has been scarcely discussed.

The creation of new biologically active compounds is a promising area of modern medicinal chemistry. Heterocyclic systems play an important role in this process.Among them, it is necessary to note 1,2,4-triazole and xanthine, the presence of which in the structure of known medicines determines their pharmacological activity. The combination of these heterocycles within a single molecule can lead to the enhancement of the existing biological effect or the emergence of new useful properties. The aim of the work has been to synthesize new theophylline-containing 4-amino-1,2,4-triazole-3-thi
