A simple approach is described for the regioselective C-3 methylsulfanylation of imidazo[1,2-a] pyridines through diiodine-mediated, acetone-promoted, C-S bond construction with dimethyl sulfoxide as both the source of the methylsulfanyl moiety and the solvent. Preliminary mechanistic investigations indicated that three different reaction mechanisms might be involved in the transformation.
