Procedure

To 1,1-dimethylethyl 4-(4-amino-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (200 mg, 0.505 mmol), and 1-[(3-methylphenyl)acetyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indole (228 mg, 0.606 mmol) dissolved in 1,4-Dioxane (4 mL) was added saturated aqueous NaHCO3 (2 mL). The mixture was then bubbled with N2 gas for 10 minutes and then Pd(Ph3P)4 (58.3 mg, 0.050 mmol) was added and then bubbled for 5 additional minutes. Then reaction was then capped and heated at 100° C. overnight. The mixture was allowed to cool then diluted with water (10 mL) then extracted with EtOAc (3×20 ml). The organics were combined, washed with brine, dried over MgSo4, filtered and concentrated to isolate a amber color oil. The oil was then purified on a 25 g Biotage SNAP column conditioned with Hexane and eluting with a gradient of 0 to 10% MeOH in DCM for 30 minutes to afford 1,1-dimethylethyl 4-(4-amino-5-{1-[(3-methylphenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (230 mg, 80% yield) as a amber color oil. 1H NMR (400 MHz, DMSO-d6) δ 8.14 (s, 1H), 8.13 (s, 1H), 7.45 (s, 1H), 7.32 (s, 1H), 7.20-7.26 (m, 2H), 7.12 (s, 1H), 7.09 (t, J=7.58 Hz, 2H), 4.71-4.83 (m, 1H), 4.20 (t, J=8.46 Hz, 2H), 4.08-4.15 (m, 2H), 3.94 (s, 2H), 3.82 (s, 2H), 3.20 (t, J=8.46 Hz, 2H), 2.95 (br. s., 2H), 2.31 (s, 3H), 1.86-1.97 (m, 4H), 1.43 (s, 9H).
