Procedure

Dimethyl-(1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-amine 109 (5.0 g, 28 mmol), was dissolved in N,N-dimethylformamide (80.0 mL) and sodium hydride (60% dispersion in mineral oil, 1.25 g, 31.4 mmol) was added, followed by triisopropylsilyl chloride (6.3 mL, 30.0 mmol). The reaction was stirred at room temperature for 12 hours, then poured into water and extracted with ethyl acetate. The organic portion was washed with brine, dried over sodium sulfate, concentrated and purified with silica gel chromatography to give the compound (110, 6.5 g, 70%).
