The 1,5-disubstitutedimidazole system was regioselectively assembled via an improved Marckwald imidazole synthesis. A new imidazole dethionation procedure has been developed to convert the Marckwald mercaptoim-idazole product to the desired imidazole. This methodology was found to be tolerant of a variety of functional groups providing good to excellent yields of 1,5-disubstitutedimidazoles. A new
