実験手順

A solution of 1-iodo-3-[3-(4-methyl-piperazin-1-yl)-cyclobutyl]-imidazo[1,5-a]pyrazin-8-ylamine (93 mg, 0.22 mmol), 8-fluoro-2-phenyl-7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)quinoline (87 mg, 0.25 mmol) and cesium carbonate (88 mg, 0.27 mmol) in DME (3.33 mL) and H2O (0.67 mL) was degassed with N2 for 10 minutes. Tetrakis(triphenylphosphine)palladium(0) (13 mg, 0.011 mmol) was added, and the reaction heated at 75° C. overnight. The reaction was allowed to cool to rt, poured into saturated NaHCO3 solution (50 ml) and extracted with ethyl acetate (3×50 ml). The combined organics were washed with brine (3×50 ml), dried (MgSO4), filtered and concentrated in vacuo. Flash chromatography (DCM stepping up to 5% MeOH in DCM) gave the title compound as an off-white solid; 1H NMR (CDCl3, 400 MHz) δ 8.27 (1H, d, J=8.6 Hz), 8.23 (2H, d, J=7.1 Hz), 7.99 (1H, d, J=8.8 Hz), 7.73-7.67 (2H, m), 7.55-7.48 (3H, m), 7.16 (1H, d, 5.1 Hz), 7.05 (1H, d, J=5.1 Hz), 3.46 (1H, m), 2.94 (1H, m), 2.71-2.32 (15H, m); MS (ES+): m/z 508.03 [M+]; HPLC: tR=1.71 min (MicromassZQ, polar—5 min).
