Procedure

To 5-[(1-benzenesulfonyl-5-methoxy-1H-pyrrolo[2,3-b]pyridin-3-yl)-hydroxy-methyl]-6-fluoro-pyridin-2-yl-(6-trifluoromethyl-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (576, 0.100 g, 0.15 mmol) in acetonitrile (12.6 mL) were added triethylsilane (0.34 mL, 2.10 mmol) and trifluoroacetic acid (0.17 mL, 2.20 mmol). The reaction was heated to 80° C. for 2 hours. The reaction was 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 to give the crude compound (577, 90 mg, 100%) that was used in the next step without further purification.
