A directconversion of 2-aminopyridine into 2,3-disubstitutedimidazo[1,2-a]pyridines was studied. A series of products was obtained in an efficient, simple and fast protocol. The scope and limitation of the transformation are also studied and was found that its effectiveness and the type of the substituent at 3-position, 3-(1-arylethane) and/or 3-(1-arylethene), is strongly dependent both on the catalyst
