Reaktionsschritte

5-bromo-4-fluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (2.0 g, 7.7 mmol) was placed in 6M HCl (30 mL) at room temperature. SnCl2 (7.29 g, 38.5 mmol) was then added, and the reaction was stirred for 30 minutes at room temperature. The reaction was then cooled to 0° C. and a saturated aqueous solution of Na2CO3 was added to raise the pH to 8. The reaction was then extracted with DCM (with minimal MeOH to aid solubility). The combined organic fractions were dried, filtered, and concentrated to give the crude product 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.50 g, 28.2% yield), which was used without purification.
