실험 절차

A mixture of cis-3-iodo-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1.89 g, 4.28 mmol, 1 equiv), tert-butyl N-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbamate (1.64 g, 5.14 mmol, 1.2 equiv), tetrakis(triphenylphosphine)palladium (0.271 g, 0.257 mmol, 0.06 equiv), and sodium carbonate monohydrate (1.28 g, 10.3 mmol, 2.4 equiv) in water (13 mL) and DME (18 mL) was heated at 85° C. for 14 h. The mixture was allowed to cool to ambient temperature. Saturated aqueous sodium bicarbonate solution (15 mL) was added and the aqueous portion was extracted with EtOAc (30 mL). The organic extract was dried over MgSO4, filtered, and concentrated to afford a pale yellow solid. Purification by column chromatography on silica gel (elution with 2 L of 95:4:1 CH2Cl2:Et3N:MeOH) afforded cis-tert-butyl N-(3-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)carbamate as a white solid (1.76 g, 3.47 mmol):
