A method for regiospecific electrophilic substitution of 3-(methylthio)thiophene in either the 2- or 5-position has been developed on the basis of a combination of bromination, metal-halogen exchange, and controlled rearrangement of 2-bromo-5-lithio-3-(methylthio)thiophene to 5-bromo-2-lithio-3-(methylthio)thiophene.
