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
