Microwave-Assisted Synthesis of New Schiff Bases from Imidazo[1,2-a]pyridine-3-carbaldehyde and Aromatic Amines in PEG-400 as a Green Approach
We have developed a short and highly efficient microwave-enhanced protocol for the synthesis of new Schiff bases, ( E )- N -[(2-arylimidazo[1,2- a ]pyridine-3-yl)methylidene]pyridin-2-amines, by the condensation of 2-arylimidazo[1,2- a ]pyridine-3-carbaldehydes with 2-aminopyridine in polyethylene...
