실험 절차

A suspension of 3-iodo-1-tetrahydro-1H-3-pyrrolyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine hydrochloride (2.186 g, 5.96 mmol) in ethylene glycol dimethyl ether (50 mL) was treated with N2-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1-methyl-1H-2-indolecarboxamide (2.66 g, 6.56 mmol), tetrakis(triphenylphosphine)palladium (0.413 g, 0.358 mmol), and a solution of sodium carbonate (2.65 g, 25.03 mmol) in water (25 mL). The reaction mixture was stirred for 24 h at 80° C. The organic solvent was removed under reduced pressure. Dichloromethane (100 mL) and 1N sodium hydroxide (50 mL) were added. The product precipitated out of the aqueous layer. The aqueous layer was evaporated under reduced pressure. The resulting solid was washed with copious amounts of dichloromethane and ethyl acetate. The organic solvent was removed under reduced pressure to give 2.218 g (77%) of pure N2-[4-(4-amino-1-tetrahydro-1H-3-pyrrolyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl]-1-methyl-1H-2-indolecarboxamide. 1H NMR (DMSO-d6, 400 MHz) δ 9.443 (s, 1H), 8.256 (s, 1H), 8.1168-8.0965 (d, 1H, J=8.12 Hz), 7.7181-7.6983 (d, 1H, J=7.92 Hz), 7.598-7.5778 (d, 1H, J=8.08 Hz), 7.349-7.291 (m, 4H), 7.171-7.132 (m, 1H), 5.332-5.313 (m, 1H), 4.041 (s, 3H), 3.96 (s, 3H), 3.224-3.058 (m, 3H), 2.926-2.910 (m, 1H), 2.213-2.158 (m, 2H); LCMS (Thermoquest AQA single-quad MS, Genesis C18 column, 3 μm particle size, 33×4.6 mm; 70% 50 mM ammonium acetate in water to 95% acetonitrile over 6 min, 0.8 to 0.5 mL/min) Rt 2.09 min (100%), MH+ 483.3.
