N-Protected o- and p-anisidines (2- and 4-methoxyanilines) undergo a hydrogen/metal exchange at the position adjacent to either the oxygen or nitrogen atom depending on what organometalic base is employed. These synthetically useful findings support previous views about neighboring group/reagent interactions.
