실험 절차

Cold (about 0 to about 5° C.) fuming nitric acid (10 mL) was added to 5-ethoxy-4-fluoro-1H-pyrrolo[2,3-b]pyridine (340 mg, 0.944 mmol). The reaction was stirred at 0° C. for 15 minutes and then ice was added. The resulting solid was filtered and dried to yield 5-ethoxy-4-fluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (165 mg, 78% yield) as a solid.
