Regioselective alkoxydehalogenation of 2,4-dichloro- and 2,4-dibromo-quinoline with solid sodium alkoxide in toluene gives the 2-alkoxy-4-halogenoquinolines 7–10, identified by 1H and 13C NMR spectroscopy. Bromination of 2-methoxyquinoline occurs at the 6- and 8-positions and does not give the 4-bromo derivative as originally reported.
