Abstract
Abstract 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.
