Participants

Reaction Steps

To (3-dibenzylamino-2,6-difluoro-phenyl)-(5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (55, 0.84 g, 1.6 mmol) in tetrahydrofuran (150 mL) was added sodium hydride (210.0 mg, 60% in mineral oil, 5.3 mmol) under an atmosphere of nitrogen. The reaction was stirred for 5 minutes. Triisopropylsilyl chloride (0.80 mL, 3.8 mmol) was added and the reaction was stirred at room temperature for 3 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 10% ethyl acetate in hexane to provide the compound (56, 420 mg, 39%). MS(ESI) [M+H+]+=687.4.
