Regioselective Suzuki coupling on pyridinium N-(3,5-dibromoheteroar-2-yl)aminides

A regioselective Suzuki–Miyaura cross-coupling reaction on 3′,5′-dibromo pyridinium N-(2′-azinyl)aminides is reported. A series of 3′-aryl(or heteroaryl)-5′-bromo-pyridinium N-(2′-pirazinyl)aminides were obtained in good yields. Two isomeric 3′,5′-diaryl pyridinium N-(2′-azinyl)aminides were also prepared.
