実験手順

Into a 250-mL 3-necked round-bottom flask purged and maintained under an inert atmosphere of nitrogen, was placed a solution of tert-butyl (3R)-3-[4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate (500 mg, 1.13 mmol, 1.00 equiv) in 1,4-dioxane/H2O (100/30 mL), 2-[4-(2,5-difluorophenoxy)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (420 mg, 1.26 mmol, 1.1 equiv), sodium carbonate (240 mg, 2.26 mmol, 2.0 equiv), and Pd(PPh3)4 (65 mg, 0.06 mmol, 0.05 equiv). The resulting solution was stirred for 12 h at 90° C. in an oil bath and then concentrated under vacuum. The residue was diluted with water and the resulting solution was extracted with dichloromethane and the organic layers were combined. The combined organics were washed with brine, dried over anhydrous sodium sulfate and concentrated. The residue was loaded onto a silica gel and eluted with dichloromethane/methanol (10/1) to give 510 mg (87%) of tert-butyl (3R)-3-[4-amino-3-[4-(2,5-difluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate as a white solid.
