Sodium Hydroxide → 5-ethoxy-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine

Participants

Reaction Steps

Tin chloride (674 mg, 3.55 mmol) was added to 5-ethoxy-4-fluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (160 mg, 0.711 mmol) in 6N HCl (5 mL) at about 0 to about 5° C., and then the reaction was stirred at 0 to about 5° C. for 2 hours. The solution was neutralized by addition of 6N NaOH and then extracted with CHCl3/IPA (3:1). The combined organic phases were dried over MgSO4 and concentrated to leave 5-ethoxy-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (120 mg, 86% yield) as a solid.
