실험 절차

(5-Bromopyridine-2,3-diyl)dimethanediyl dimethanesulfonate (17.0 g, 45.4 mmol) was added to a mixture of 1-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (prepared according to the procedures described in WO2008/020902, 14.0 g, 53.0 mmol) and cesium carbonate (49.0 g, 150 mmol) in ethanol (500 mL) 23° C., and the resulting mixture was stirred for 20 h. The reaction mixture was concentrated then partitioned between ethyl acetate (500 mL) and water (500 mL). The organic layer was dried over magnesium sulfate and concentrated. The residue was purified via silica gel chromatography (heptane initially, grading to 100% EtOAc) to give the title compound. MS: m/z=448.1 (M+1).
