Versuchsvorschrift

A mixture of benzyl N-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbamate (9.54 g, 0.027 mol), tert-butyl 4-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-piperidinecarboxylate (10.0 g, 0.0225 mol), tetrakis(triphenylphosphine)palladium (1.56 g, 0.00135 mol) and sodium carbonate (5.97 g, 0.0563 mol) was heated in a mixture of ethylene glycol dimethyl ether (120 mL) and water (60 mL) at 80° C. for 16 hours under an atmosphere of nitrogen. The mixture was allowed to cool to ambient temperature and solvents were removed under the reduced pressure. The residue was partitioned between water (150 mL) and dichloromethane (150 mL); the organic phase was washed with brine, dried with magnesium sulfate and concentrated under reduced pressure. The residue was triturated in diethyl ether and the precipitate was collected by filtration and dried to yield tert-butyl 4-[4-amino-3-(4-[(benzyloxy)carbonyl]aminophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-piperidinecarboxylate (10.1 g, 0.0186 mol) as a white solid.
