Reaction Steps

Potassium carbonate (1.20 g, 8.69 mmol) was added to a solution of 1-(5-nitro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)ethanone (0.50 g, 1.45 mmol) in methanol (13 mL) and water (4.3 mL). The reaction mixture was heated at 40° C. for 30 minutes. The reaction mixture was then cooled down and treated with water and ethyl acetate. The layers were then separated. The organic layers were washed twice with water, dried over sodium sulfate, filtered, and evaporated to afford 1-(5-nitro-1H-pyrrolo[2,3-b]pyridin-2-yl)ethanone (0.30 g, quantitative yield).
