実験手順

To 1,1-dimethylethyl 4-(4-amino-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (138 mg, 0.348 mmol), and 1-[(2,5-difluorophenyl)acetyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indole (167 mg, 0.418 mmol) were dissolved in 1,4-Dioxane (5. mL) then added saturated NaHCO3 (2 mL). The mixture was then bubbled with N2 gas for 10 min then Pd(Ph3P)4 (40.2 mg, 0.035 mmol) was added, and then the mixture was bubbled for 5 additional minutes. The reaction was then capped and heated at 100° C. for 4 hr. The mixture was allowed to cool then diluted with water (10 mL) then extracted with EtOAc (3×20 ml). The organic were combined, washed with brine, dried over MgSO4, filtered and concentrated to isolated a amber color oil. The oil was then purified on a 25 g Biotage SNAP column conditioned with Hexane eluting with a gradient of 0 to 10% MeOH in DCM for 30 min. to give 1,1-dimethylethyl 4-(4-amino-5-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (160 mg, 0.272 mmol, 78% yield) as a amber color oil. LC/MS (ES) m/z=589.6 [M+H]+.
