An efficient and green protocol for synthesis of 3-aminoimidazo[1,2-a] pyridine derivatives through a three-component reaction of aldehyde, 2-amino pyridine and isocyanide in the presence of silica-supportedperchloricacid (HClO4-SiO2) is described in this paper. The solid catalyst could be recycled and reused.
