실험 절차

Into a 100 mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed tert-butyl (3R)-3-[4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate (300 mg, 0.68 mmol, 1.00 equiv), 2-[4-(3-fluorophenoxy)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (255 mg, 0.81 mmol, 1.20 equiv), sodium carbonate (143 g, 1.35 mol, 1998.01 equiv), ethylene glycol dimethyl ether (50 mL), water (15 mL), and Pd(PPh3)4 (40 mg, 0.03 mmol, 0.05 equiv). The resulting solution was stirred overnight at 80° C. and then concentrated under vacuum. The residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (100/1) to give 260 mg (76%) of tert-butyl (3R)-3-[4-amino-3-[4-(3-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate as a yellow solid.
