Versuchsvorschrift

To {5-[(5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-hydroxy-methyl]-pyridin-2-yl}-(4-chloro-benzyl)-carbamic acid tert-butyl ester (45, 180.0 mg, 0.33 mmol) in acetonitrile (30.0 mL) were added trifluoroacetic acid (2.0 mL, 0.026 mol) and triethylsilane (4.0 mL, 0.025 mol). The reaction was heated to reflux for 4 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified by silica gel column chromatography eluting with 10% methanol in dichloromethane to give compound (P-0038, 120 mg, 85.2%). MS (ESI)[M+H+]+=427.2, 429.2.
