Synthesis of triphenylamine-imidazo[1,2-a]pyridine via Groebke-Blackburn-Bienaymé Reaction

A series of triphenylamine-imidazo[1,2-a]pyridine were synthesized in moderate yields (57–67%) by Groebke–Blackburn–Bienayme reaction (GBBR) under catalyst and solvent green conditions. The molecules synthesized containing triphenylamine and imidazo[1,2-a]pyridines cores which are considered a privileged cores exhibited fluorescence and medicinal properties.
