To a solution of (2-ethoxy-3-hydroxy-phenyl)-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (666, 84 mg, 0.054 mmol) in methanol (10 mL) was added potassium hydroxide (6 N solution) until pH of the solution turned to over 10. Potassium fluoride (30 mg, 0.5 mmol) was then added to the reaction mixture and the mixture was stirred at room temperature for 6 hours. The reaction mixture was then poured into saturated sodium carbonate and was extracted with ethyl acetate. The organic layer was collected and washed with brine, dried over magnesium sulfate. After removal of the solvent, the residue was purified by preparative HPLC to provide as a white solid (P-2094, 5 mg, 19%). MS (ESI) [M+H+]+=485.17.
