A palladium-catalyzed N-alkylation of anilines with tertiary amines that occurs under heterogeneous transfer-hydrogenation conditions has been developed (see scheme). This protocol of transamination, which uses a relatively cheap and easily recyclable heterogeneous catalyst, can be efficiently applied to different substrates and is suitable for large-scale preparations.
