Procedure

A mixture of (4-Chloro-benzyl)-{4-chloro-5-[hydroxy-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-thiazol-2-yl}-carbamic acid tert-butyl ester (97, 76 mg, 0.11 mmol), triethylsilane (0.5 mL, 3 mmol), and trifluoroacetic acid (0.25 mL, 3.2 mmol) in acetonitrile (5 mL) was refluxed for 3 hours. The reaction mixture was poured into iced water, extracted with ethyl acetate, washed with sodium bicarbonate, brine, and dried over sodium sulfate. After removal of solvent, the residue was purified by silica gel column chromatography eluting with ethyl acetate in hexane to provide the compound as a yellow solid (P-0083, 5.6 mg, 14%). MS (ESI) [M+H+]=389.35, 390.36.
