Procedure

A suspension of 1-[3-(1H-1-imidazolyl)propyl]-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.086 g, 0.233 mmol) in ethylene glycol dimethyl ether (4 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 (0.104 g, 0.256 mmol), tetrakis(triphenylphosphine)palladium (0.016 g, 0.014 mmol), and a solution of sodium carbonate (0.059 g, 0.56 mmol) in water (2 mL). The reaction mixture was stirred for 24 h at 80° C. The organic solvent was removed under reduced pressure and dichloromethane (25 mL) was added. The layers were partitioned and the aqueous layer was extracted with dichloromethane (100 mL). The combined organic layers were dried over magnesium sulfate, filtered and evaporated under reduced pressure. The crude material was purified by flash chromatography on silica gel using a step-wise gradient of 5% methanol in dichloromethane to 50% methanol in dichloromethane on a 10 g ISCO column. The column afforded 0.06 g (49%) of pure N2-(4-{4-amino-1-[3-(1H-1-imidazolyl)propyl]-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), 8.278 (s, 1H), 8.1324-8.1121 (d, 1H, J=8.12 Hz), 7.744-7.699 (m, 2H), 7.6-7.579 (d, 1H, J=8.4 Hz), 7.365-7.283 (m, 5H), 7.172-7.135 (m, 1H), 6.939 (s, 1H), 4.36-4.326 (m, 2H), 4.079-4.019 (m, 5H), 3.964 (s, 3H), 2.324-2.309 (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 2.25 min (100%), MH+ 522.3.
