In this study, twenty-nine 2-aminopyrimidine derivatives are synthesized in good to excellent yields by fusing 2-amino-4,6-dichloropyrimidine with different amines in the presence of triethylamine without using any solvent or catalyst. Nucleophilic substitution reactions of 2-amino-4,6-dichloropyrimidine with amines have also been performed in ethanol. Comparisons of the yields and reaction times for both solvent and solvent-free conditions have shown that the newly developed solvent-free protocol is high yielding, more efficient, and simpler compared to conventional methods.

Synthesis of 2-Aminopyrimidine Derivatives and Their Evaluation as β-Glucuronidase Inhibitors: In Vitro and In Silico Studies
evaluated for their β-glucuronidase inhibitory activity, and among them, compound 24 (IC50 = 2.8 ± 0.10 µM) showed an activity much superior to standard D-saccharic acid 1,4-lactone (IC50 = 45.75 ± 2.16 µM). To predict the binding mode of the substrate and β-glucuronidase, in silico study was performed. Conclusively, this study has identified a potentβ-glucuronidaseinhibitor that deserves to be further
