Sonication Assisted One-Pot Synthesis of Substituted Imidazopyridine from Styrene in Water.

The present protocol is a simple and eco-friendly approach for the one-pot procedure for the synthesis of substituted imidazopyridines ranging from important feedstock's like styrene promoted by NBS. Through sonicator and microwave commercially available styrene with NBS in water followed by reaction with 2- aminopyridines afforded important heterocyclic scaffolds in an one-pot procedure.
