Anilinate, anilinate! A method for arylation of anilines directed by an N-2-pyridyl group is developed. The reaction is tolerant towards a large number of substituents on both the aniline and the boronic acid, which is used as aryl donor. Although often considered a permanent directing group, the pyridine group is removed efficiently to give ortho-arylated aniline derivatives.
