3-(Hetero)arylmethyl derivatives of imidazo[1,2-a]pyridine have been synthesized by a novel one-pot method consisting of the Sonogashira coupling of tert-butyl prop-2-yn-1-yl(pyridin-2-yl)carbamate with different substituted (hetero)aryl bromides and cyclization of the in situ obtained intermediate substituted (hetero)aryl acetylene derivatives.
