Abstract
In this research, synthesis of different imidazopyridine derivatives was performed using aryl glyoxals, thiobarbituric acid, and 2-aminopyridine in the presence of acetic acid in ethanol at 80 °C. Different aryl glyoxals can be used in this method. Finally, the desired products were separated by simple filtration in excellent yields. The salient features of this protocol are a simple operation, mild reaction conditions, simple work up, easy product isolation, and preparation of potentially bioactive compounds.
