A practical and efficient protocol for the syntheses of 6-substituted 2-bromopyridine compounds has been developed by using a selective copper-catalyzedC–N bond-forming reaction between 2,6-dibromopyridine and a range of amines. The major advantage of this protocol is the complete control of selectivity of the pyridine bromine atom for the C–N cross-coupling reaction. There are few reported syntheses

of the pyridine ring to generate monosubstituted halogenated pyridines with high selectivities. Different halogen atoms at various positions were produced by the pyridine ring that performed well under mild conditions. Halogenated pyrimidines underwent highly selective coupling at the chloride group with a wide range of amines having broad substrate applicability and moderate to good yields. The selectivity
