The present invention relates to processes for the preparation of heteroaryl ethers. In some embodiments, the processes relate to cross coupling reactions between triazol-1-yloxy and triazol-1-yl heterocycles with aryl boronic acids. In a further aspect, this invention also relates to compounds that are useful for the treatment of oncological diseases or disorders, and for the treatment of inflammation.

Pyridotriazol-1-yloxypyrimidine 3 reacts with arylboronic acids under palladium-free, Cs2CO3, (0.8%) H2O2, and DME conditions to produce heteroaryl ethers 4-16 in good yields comparable to the oxidative palladium-catalyzed reaction. The yields of aryl ethers 17-19 from quinazoline 2 with (0.8%) H2O2 were modest. Hydrogen peroxide is Superior to dioxygen as an oxidant in these reactions. (C) 2009 Elsevier Ltd.
