Reaction Steps

To N-{2,4-difluoro-3-[hydroxy-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-phenyl}-3-methoxy-benzenesulfonamide (92, 0.075 g, 0.12 mmol) in tetrahydrofuran (3.0 mL), was added tetra-n-butylammonium fluoride (0.039 g, 0.15 mmol). The reaction was stirred at room temperature for 20 minutes. The reaction was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 3% methanol in dichloromethane to give light yellow solid (93, 0.030 g, 55%). MS (ESI) [M+H+]+=446.
