Reaction Steps
To a suspension of sodium hydride (934 mg, 0.0358 mol) in DMF (57 mL) was added dropwise under N2, a solution of 1H-pyrrolo[2,3-b]pyridine (3.00 g, 0.0254 mol) in DMF (20 mL). The mixture was stirred at r.t. for 45 min. then cooled to 0° C. and treated dropwise with [2-(trimethylsilyl)ethoxy]methyl chloride (6.32 mL, 0.0357 mol). The mixture was stirred at rt for 12 h. then poured into water (10 mL), stirred for 30 min. and extracted with Et20 (4×10 mL). The combined extracts were washed with brine (20 mL), dried over sodium sulfate, and concentrated in vacua to give the crude product which was chromatographed over silica gel eluting with hexane→1:9 Et2O: hexane to afford 6 g desired product.
