2-Acetylaminoisonicotinic Acid is a reactant in the preparation of nicotinic acid analogues as potent-hypoxia inducible factor (HIF)-1α inhibitors. | [Synthesis]
b) Synthesis of 2-acetamido pyridine-4-carboxylic acid (3): 214.0 g of 2-(acetamido)-4-methylpyridine (2) was added in batches to an aqueous solution of 160 g of potassium permanganate at 50 °C while maintaining stirring. An additional 360 g of potassium permanganate was added in batches over a period of 1 hour, during which the temperature of the reaction mixture needed to be controlled not to exceed 90 °C. After completion of the reaction, stirring was continued for 1.5 hours, followed by thermal filtration. The pH of the filtrate was adjusted to 3-4 with concentrated hydrochloric acid, and the white precipitate precipitated was 2-acetylaminopyridine-4-carboxylic acid (3). After separation by filtration and drying under vacuum conditions, 108.0 g of product was obtained in 42% yield. | [References]
