To a degassed mixture of 141 mg [6-Bromo-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridin-4-yl]-methanol, 95 mg 4-(methoxymethoxy)phenylboronic acid and 65 mg potassium carbonate in DME/water (v/v=2/1, 2.3 mL) at r.t. and under Ar-atmosphere 6 mg palladium(0) bis(tri-tert-butylphosphine) was added and the mixture was stirred at 85° C. for 40 min in a microwave reactor. Then 6 mg palladium(0) bis(tri-tert-butylphosphine) and 95 mg 4-(methoxymethoxy)phenylboronic acid were added and the mixture was stirred at 100° C. for 20 min. To the mixture water and ethyl acetate were added, the phases were separated and the aqueous phase was extracted with ethyl acetate. The combined organic phases were concentrated in vacuo and the residue was triturated with ethyl acetate. The resulting solid was isolated by filtration. 171 mg (100%) of the title compound were obtained.
