실험 절차

To a solution of 5,6-bis(bromomethyl)pyridine-2-carbonitrile from Step C (1.80 g, 6.21 mmol) and 1-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (1.64 g, 6.21 mmol, described in Intermediate 2) in DMF (207 mL) was added cesium carbonate (6.07 g, 18.6 mmol), portionwise, over 5 min. After 18 h, the mixture was partitioned between CH2Cl2 (100 mL), saturated aqueous NaHCO3 (100 mL) and brine (200 mL). The organic layer was removed and the aqueous layer was extracted further with CH2Cl2 (2×100 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of hexane:EtOAc—100:0 to 10:90, to give the title compound. MS: m/z=393 (M+1).
