3-Acyl imidazo[l,2-a]pyridines with no substituent at position 2 were obtained in moderate to good yields in an improved version of the Tisler protocol for the synthesis of imidazo[l,2-x]azines. It was found that yields are significantly improved if the reaction is carried out in the presence of DMF or in some cases in the absence of a solvent.
