実験手順

A microwavable vial was charged with 6-[(6-bromo-1H-imidazo[4,5-b]pyridin-2-yl)methyl]-3-(2,4,6-trifluorobenzoyl)-1,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7-one (20 mg, 0.04 mmol), [1-(tert-butoxycarbonyl)-1H-pyrrol-2-yl]boronic acid (12.6 mg, 0.06 mmol), cesium carbonate (39 mg, 0.119 mmol), bis(triphenylphosphine)palladium(II) chloride (2.8 mg, 3.98 umol) and acetonitril/water (0.6/0.2 ml). The vial was sealed, purged by 3 cycles of freeze-pump-thaw. The resultant suspension was heated to 135° C. by microwave irradiation for 15 min. LCMS showed complete consumption of the starting material and formation of the desired product. The reaction mixture was diluted with acetonitrile, and filtered through a 0.45 micron membrane filter and then concentrated to dryness under reduced pressure. The crude reaction mixture was purified by HPLC on Xbridge (C18 5u particle size, 30×75 mm) preparative column eluting with a linear gradient of 15-40% acetonitrile/water (0.01% NH4OH) at 70 ml/min. to give the title compound (1.6 mg, 8%). MS (ESI): m/z 489 (M+H). 1H-NMR (500 MHz, d6-DMSO): δ 11.35 (br. s, 1H), 8.61 (s, 1H), 8.03 (s, 1H), 7.89 (s, 1H), 7.58 (d, 1H), 7.36 (m, 2H), 7.00 (d, 1H), 6.86 (s, 1H), 6.54 (s, 1H), 6.11 (s, 1H), 5.47 (s, 2H),
