200 mg (0.52 mmol) of 3-(5-bromo-2-pyrimidinyl)-1-(2-fluorobenzyl)-1H-pyrazolo-[3,4-b]pyridine (example I, step 6), 90 mg (0.62 mmol) of 2-(hydroxymethyl)-phenylboronic acid, 40 mg (0.05 mmol) of 1,1′-bis(diphenylphosphino)-ferrocenepalladium(II) chloride and 200 mg (0.62 mmol) of cesium carbonate are taken up in 2 ml of DME and stirred under reflux overnight. The solvent is removed under vacuum, and the residue is purified by preparative HPLC to result in 111 mg (52% of theory) of the product.
