実験手順
5-Chloro-4-fluoro-1H-pyrrolo[2,3-b]pyridine (1.2 g, 7.0 mmol) was added slowly to fuming nitric acid (10 mL) at 0° C. Upon completion of the addition, the reaction was stirred for 10 minutes, and then quenched with ice. Water was added until a precipitate formed, which was filtered, washed with water and dried to give the product 5-chloro-4-fluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (1.3 g, 86% yield).
