Reaction Steps

3-Iodo-1H-pyrrolo[2,3-b]pyridine 36 (1.11 g, 4.6 mmol) was dissolved in tetrahydrofuran (120 mL). Sodium hydride (60% dispersion in mineral oil, 0.13 g, 5.5 mmol) was added, followed by tert-butyldimethylsilyl chloride (0.85 g, 5.5 mmol). The reaction was stirred at room temperature overnight. The reaction was poured into water and extracted with ethyl acetate. The organic portion was washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified with silica gel column chromatography eluting with 30% ethyl acetate in hexane to give the compound as a white solid (38, 100 mg, 15%).
