Reaction Steps

To a solution of 4,5-bis(bromomethyl)-2-chloropyridine from Step D (254 mg, 0.85 mmol) and 1-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one (226 mg, 0.86 mmol, described in Intermediate 4) in DMF (8 mL) was added cesium carbonate (455 mg, 1.40 mmol). After 21 h, the reaction mixture was poured into H2O (60 mL) and extracted with EtOAc (2×60 mL). The organic layer was washed with brine (40 mL), then dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of hexanes:EtOAc—100:0 to 0:100, to give the title compound. MS: m/z=402 (M+1).
