Procedure

4,5-Difluoro-1H-pyrrolo[2,3-b]pyridine (0.63 g, 4.09 mmol) was added slowly to fuming nitric acid (8.18 mL, 164 mmol) at 0° C. and stirred slowly for 5 minutes. Ice (20 g) was added followed by water (40 mL). The solid formed was collected by filtration to give 4,5-difluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (0.65 g, 80% yield) as a solid.
