Abstract

The palladium-catalyzed N-(hetero)arylation of a number of heteroarylamines including 2-aminopyridines, 2-aminothiazoles, and their analogues has been realized using Xantphos as the ligand. Weak bases such as Cs2CO3, Na2CO3, and K3PO4 were used in most cases to allow for the introduction of functional groups. Choice of the base and solvent was critical for the success of these reactions.
