실험 절차

To a solution of rac-tert-butyl 3-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyrrolidinecarboxylate (0.412 g, 0.958 mmol) in ethylene glycol dimethyl ether (6 mL) and water (3 mL) was added N2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-5,7-dimethyl-1,3-benzoxazol-2-amine (0.436 g, 1.20 mmol), tetrakis(triphenylphosphine) palladium (0) (0.055 g, 0.048 mmol), and sodium carbonate (0.254 g, 2.39 mmol). The solution was heated at 80° C. for 18 h, and then cooled to room temperature. The reaction mixture was partitioned between ethyl acetate (10 mL) and water (10 mL). The organic layer was separated and washed with brine (10 mL), dried over anhydrous magnesium sulfate, filtered, and concentrated to afford rac-tert-butyl 3-(4-amino-3-{4-[(5,7-dimethyl-1,3-benzoxazol-2-yl)amino]phenyl}-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyrrolidinecarboxylate as an orange solid (1.029 g), which was used in the next step without further purification.
