N-(6-bromo-pyridin-2-yl)-pyridine-2,6-diamine (bppd) in 96% yield. Pyridine was then used in the second step of the aminated coupling for 4-toluenesulphonyl chloride and bppd. Finally, the monoamination was facilitated by the palladium-catalyzed Buchwald's coupling reaction, and subsequently the corresponding metal complexes of these bifunctional ligands were constructed.
