Versuchsvorschrift
SnCl2 dihydrate (0.85 g, 3.77 mmol) at a temperature of about 0° C. to about 5° C. was added to 4-chloro-3-nitro-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridine (0.20 g, 0.75 mmol) in 6M HCl (5 mL). The mixture was stirred at room temperature for 2 hours, and was then 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-chloro-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-amine (0.16 g, 89% yield) was isolated as a solid.
