To 1-Triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid methyl ester (531, 0.950 g, 2.9 mmol) in tetrahydrofuran (20.0 mL) was added tetrabutyl-ammonium fluoride, trihydrate (1.20 g, 3.8 mmol). The reaction was stirred at room temperature for 10 minutes. The reaction was concentrated and purified with silica gel column chromatography eluting with 4% methanol in methylene chloride to give the compound as a white solid (532, 300 mg, 60%). MS (ESI) [M+H+]+=177.2.
