Participants

Reaction Steps

A mixture of acetic acid 1-acetyl-1H-pyrrolo[2,3-b]pyridin-6-yl ester (4.0 g, 18.3 mmol) and potassium carbonate (10.45 g, 75.7 mmol) in methanol/water (50%, 260 mL) was stirred at room temperature for 12 h. The reaction mixture was concentrated to half its volume and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and evaporated. The residue was purified by flash column chromatography (silica gel from QingDao, 200-300 mesh, 10% methanol/dichloromethane) afforded 1H-pyrrolo[2,3-b]pyridin-6-ol (1.52 g, 62%): LC/MS m/e calcd for C7H6N2O [M+H]+ 135.14, observed 135.0.
