Reaction of imidazo[1,2-a]pyridines with aliphatic aldehydes: A simple and efficient method for the preparation of novel c-3 vinylic derivatives of imidazo[1,2-a]pyridines

A simple and efficient method for the preparation of novel C-3 vinylic derivatives of imidazo[1,2-a]pyridines has been developed by the reaction of imidazo [1,2-a]pyridines with appropriate aliphatic aldehydes in acetic acid in a sealed tube.
