Versuchsvorschrift

To (4-chloro-benzyl)-6-chloro-5-[hydroxy-(1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-pyridin-2-yl-carbamic acid tert-butyl ester (542, 1.00 g, 2.00 mmol) in acetonitrile (130.0 mL) were added triethylsilane (11.5 mL, 0.0720 mol) and trifluoroacetic acid (5.5 mL, 0.071 mol). The reaction was heated to reflux for 2 hours, 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 washed with ethyl acetate and hexane to give a light yellow solid (P-0161, 480 mg, 62%). MS (ESI) [M+H+]+=383.1, 385.1.
