C5 to C2 position migrations of 2-trialkylsilyl and thiophenyl groups have been observed upon lithiation at the C5-position of corresponding C2-substituted 1-methylimidazoles.Double bromine-lithium exchange of 1-methyl-2,5-dibromoimidazole (5) affords a facile, quantitative and unequivocal synthesis of 2,5-dilithio-1-methyl-imidazole (4).Reaction of 4 with one equivalent of DMF occurs selectively at the C5 position to give 1-methylimidazole-5-carboxaldehyde.
