Bardhan, Sujata published the artcileHeteroaryl ethers by oxidative palladium catalysis of pyridotriazol-1-yloxy pyrimidines with arylboronic acids, Formula: C3H5BN2O2, the publication is Organic Letters (2009), 11(12), 2511-2514, database is CAplus and MEDLINE.
The oxidative palladium-catalyzed cross-coupling of pyrimidines containing pyridotriazol-1-yloxy (OPt) as either a urea or an amide functional group with arylboronic acids in the presence of Cs2CO3 in DME containing 0.6-1.0% H2O is described for the preparation of heteroaryl ethers. The bromo substitution in the case of 3-(5-bromo-pyrimidin-2-yloxy)-3H-[1,2,3]triazolo[4,5-b]pyridine could serve as a handle for further elaborations such as Suzuki coupling for attaching varied aryl groups.
