실험 절차

To a mixture of 5-bromo-1-(phenylacetyl)-2,3-dihydro-1H-indole (148 mg, 0.467 mmol),bis(pinacolato)diboron (125 mg, 0.491 mmol), and potassium acetate (138 mg, 1.402 mmol) was added 1,4-dioxane (6 mL), and the mixture was degassed with N2 for 10 minutes. PdCl2(dppf)-CH2Cl2 adduct (19.08 mg, 0.023 mmol) was added, and the reaction mixture was stirred for 3 hours at 100 C into a sealed vessel. The reaction was cooled down to room temperature. 3-bromo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (100 mg, 0.467 mmol) and sat. aq. NaHCO3 (2 mL) were added, and N2 gas was bubbled through the mixture for 10 minutes. PdCl2(dppf)-CH2Cl2 adduct (19.08 mg, 0.023 mmol) was added, the vessel was sealed, and the reaction mixture was stirred for 3 days at 100 C. The mixture was allowed to cool to room temperature and poured onto water (˜150 mL). The resulting mixture was filtered, and the resulting solid was triturated with EtOAc. To the dark solid in the filter was added a 80:20 mixture of CHCl3:CH3OH (˜7 mL), and the resulting mixture was filtered. The filtrate was injected into a 90 g SiO2 columns. Flash chromatography on SiO2 (gradient: 100% CHCl3 to 90:10:1 CHCl3:CH3OH:NH4OH) provided the title compound. Trituration with Et2O afforded the title compound 3-[1-(phenylacetyl)-2,3-dihydro-1H-indol-5-yl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (35 mg) as a grey solid. 1H NMR (400 MHz, DMSO-d6) 3.24 (t, J=8.34 Hz, 2H), 3.89 (s, 2H), 4.24 (t, J=8.46 Hz, 2H), 7.22-7.40 (m, 6H), 7.44 (d, J=8.34 Hz, 1H), 7.50 (s, 1H), 8.17-8.23 (m, 2H), 13.51 (s, 1H)
