Reaction Steps

Potassium carbonate (0.25 g, 1.76 mmol) was added to a solution of 2-(difluoromethyl)-5-nitro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.089 g, 0.252 mmol) in methanol (2.2 mL) and water (0.7 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 separated. The combined organic layers were washed twice with water, dried over sodium sulfate, filtered, and evaporated to afford 2-(difluoromethyl)-5-nitro-1H-pyrrolo[2,3-b]pyridine (0.032 g, 49%).
