실험 절차

To 5-bromo-7-[2-(4-morpholinyl)ethyl]-7H-pyrrolo[2,3-d]pyrimidin-4-amine (100 mg, 0.307 mmol), 1-[(2,5-difluorophenyl)acetyl]-5-(4, 4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indole (159 mg, 0.399 mmol) in a 5 ml sealable vial was added 1,4-Dioxane (2 mL) and saturated NaHCO3 (1 mL). The mixture was then bubbled with N2 gas for 10 minutes then Pd(Ph3P)4 (35.4 mg, 0.031 mmol) was added. The mixture was again bubbled N2 gas for 5 minutes then capped and the reaction was heated at 100° C. overnight. The reaction was diluted with water (3 ml) then extracted with EtOAc (3×5 ml). The organics were then combined and washed with brine, dried over MgSO4, filtered and concentrated. The residue was then dissolved in 3 ml of DMSO and purified on HPLC: (HPLC condition: Gilson using Trilution software with a Sunfire 5u C18(2) 100A. 50×30.00 mm 5 micron. 7.3-minute run (47 ml/min, 7% ACN/H2O, 0.1% TFA to 32% ACN/H2O, 0.1% TFA) with UV detection at 254 nm). Product fractions were combined and the volume was reduced to remove most of the MeCN. To the water left behind was added saturated NaHCO3 and then extracted with EtOAc (3×15 mL). The organic was combined wash with saturated NaCl solution, dried over MgSO4, filtered and concentrated. Then it was transferred into a 40 mL vial with MeCN then added water and freeze-dried to isolated 5-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-[2-(4-morpholinyl)ethyl]-7H-pyrrolo[2,3-d]pyrimidin-4-amine (76 mg, 47.8% yield) as a white solid. LC-MS (ES) m/z=519.5 [M+H]+.
