摘要：

A facile microwave assisted reaction of phenacyl bromide and 2-amino pyridine is catalyzed by Nano SiO2 under solvent free conditions to give corresponding Imidazo[1,2-a] pyridines in good yields. Reactions proceed with high efficiency and good functional group tolerance. This approach provides a useful protocol for the preparation of highly substituted Imidazo [1,2-a] pyridine derivatives.
