Reaktionsschritte

1 ml of fuming nitric acid was added to 70 mg of N-(4-(1-acetyl-3-methylpyrrolidin-2-yl)-3-fluorophenyl)pyridine-2-carboxamide, and the reaction liquid was stirred at room temperature for 2 hours. The reaction liquid was poured into a mixture of ice-aqueous saturated sodium bicarbonate, extracted with chloroform, and dried with anhydrous sodium carbonate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through partitioning thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (by Merck), chloroform/methanol=20/1) to obtain the entitled compound as a yellow solid.
