copper-catalyzed transfer N-heteroarylation strategy using a C–N bond exchange reaction is described. This reaction accommodates a wide range of pyridine and pyrimidinerings bearing halogen atoms, which have wide utility for subsequent transformations. This method provides a direct and operationally simple approach for modifying complex molecules by the exchange of N-heterocyclic substituents. A copper-catalyzed

Chlorine-containing pyrimidines are selectively hydrogenated with elimination of hydrogen chloride, without other substituents and/or the aromatic ring being significantly attacked, by using a hydrogenation catalyst and a hydrogen chloride acceptor. This process gives predominantly new pyrimidines.
