Reaction Steps
To (5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-2,6-difluoro-3-[2-(tetrahydro -pyran-2-yloxy)-ethoxy]-phenyl-methanol (542, 0.22 g, 0.46 mmol) in acetonitrile (6.0 mL) were added trifluoroacetic acid (0.14 mL, 1.8 mmol) and triethylsilane (0.29 mL, 1.8 mmol). The reaction was stirred at room temperature overnight. The filtrate was concentrated and purified by silica gel column chromatography eluting with 35% ethyl acetate in hexane to give the compound as a white solid (P-1392, 62 mg, 35%). MS (M+H+)+=383.1, 385.1.
