실험 절차

Into a 100 mL, 3-necked round-bottom flask purged and maintained under an inert atmosphere of nitrogen, was placed tert-butyl (2R)-2-([4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidine-1-carboxylate (380 mg, 0.86 mmol, 1.00 equiv), (2-fluoro-4-phenoxyphenyl)boronic acid (240 mg, 1.03 mmol, 1.20 equiv), tetrakis-(triphenylphosphane) palladium (60 mg, 0.05 mmol, 0.06 equiv), dioxane (50 mL), sodium carbonate (228 mg, 2.15 mmol, 2.50 equiv) and water (10 mL). The resulting solution was stirred for 12 h at 80° C. in an oil bath. The resulting mixture was concentrated under vacuum and the resulting solution was extracted with dichloromethane and the organic layers combined, dried and concentrated under vacuum. The residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (50/1) to give 0.347 g (80%) of tert-butyl (2R)-2-[[4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidine-1-carboxylate as a brown solid.
