Reaction Steps

To (1-benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-(2-methylsulfanyl-pyrimidin-5-yl)-methanol (608, 0.35 g, 0.78 mmol) in dichloromethane (15.0 mL) were added triethylsilane (2.00 mL, 12.52 mmol) and trifluoroacetic acid (1.00 mL, 13.0 mmol). The reaction was stirred at 35° C. overnight, then concentrated, poured into aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 20% to 100% ethyl acetate in hexane to give the desired compound (609, 0.25 g, 74%). MS (ESI) [M+H+]+=430.9.
