Procedure

To 2,4-Difluoro-3-(5-pyridin-3-yl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-phenol (549, 427.0 mg, 0.87 mmol) in tetrahydrofuran (20.0 mL) was added sodium hydride (60% in mineral oil, 42.0 mg, 1.1 mmol). 30 minutes later, methyl bromoacetate (146 mg, 0.95 mmol) was added to the reaction. The reaction was stirred at room temperature for 4 hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated to give the crude compound that was used directly in the next step.
