Procedure
SnCl2 dihydrate (3.68 g, 16.3 mmol) at a temperature of about 0° C. to about 5° C. was added to 4,5-difluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (0.65 g, 3.26 mmol) in 6M HCl (5 mL). The mixture was stirred at room temperature for 30 minutes. The mixture was neutralized to a pH of about 8 with a 6N NaOH solution. The mixture was extracted with CHCl3:IPA (3×30 mL; 3:1) and dried over sodium sulfate. After removal of the solvent, 4,5-difluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.45 g, 2.66 mmol, 81% yield) was isolated as a solid.
