실험 절차

Into a 100 mL 3-necked round-bottom flask purged and maintained under an inert atmosphere of nitrogen, was placed a solution of tert-butyl (2R)-2-([4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidine-1-carboxylate (300 mg, 0.68 mmol, 1.00 equiv) in dioxane/H2O (7/3=V/V) (30 mL), [4-(2-fluorophenoxy)phenyl]boronic acid (500 mg, 2.16 mmol, 3.19 equiv), sodium carbonate (500 mg, 4.72 mmol, 6.99 equiv), and Pd(PPh3)4 (200 mg, 0.17 mmol, 0.26 equiv). The resulting solution was stirred overnight at 100° C. in an oil bath and then concentrated under vacuum. The residue was loaded onto a silica gel column with dichloromethane/methanol (100:1) to give 0.2 g (59%) of tert-butyl (2S)-2-([4-amino-3-[4-(2-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)-pyrrolidine-1-carboxylate as a light yellow solid.
