実験手順

A mixture of tert-butyl 4-[(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl]-4-hydroxy-1-piperidinecarboxylate (0.27 g, 0.00057 mol), benzyl N-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbamate (0.26 g, 0.00068 mol), tetrakis(triphenylphosphine)palladium (0.039 g, 0.000034 mol) and sodium carbonate (0.15 g, 0.0014 mol) in ethylene glycol dimethyl ether (7 mL) and water (3 mL) was heated at 85° C. for 16 hours under an atmosphere of nitrogen. The mixture was allowed to cool to ambient temperature and ethylene glycol dimethyl ether was removed under the reduced pressure. The aqueous layer was extracted with dichloromethane (2×100 mL). The combined organic extracts were washed with water and brine, and dried over magnesium sulfate. The organic layer was filtered through silica gel twice to remove the catalyst, and the solvent was removed under reduced pressure. The residue was purified by RP-HPLC (Hypersilprep HS C18, 8 μm, 250×21.1 mm; 5%-100% over 35 min with 0.1 M ammonium acetate, 21 mL/min) to yield tert-butyl 4-{[4-amino-3-(4-{[(benzyloxy)carbonyl]amino}-3-methoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl}-4-hydroxy-1-piperidinecarboxylate (0.1 g, 0.00017 mol).
