use of diverse oxazoles 2 as suitable substrates in cross‐coupling reactions with azole‐5‐carboxylic acids 1 under palladium catalysis in the presence of copper carbonate. The reaction is successful for the synthesis of a range of bis(azole)s, and has been applied to the convergent synthesis of challenging poly azoles (dcpe=bis(dicyclohexylphosphino)ethane, DMSO=dimethyl sulfoxide, M.S.=molecular sieves)
