Versuchsvorschrift
To a solution of 6-hydroxy nicotinic acid (0.500 g, 3.59 mmol, TCI) in MeCN (20 mL), was added N-chlorosuccinimide (0.436 mL, 5.39 mmol, Aldrich). The resulting mixture was then heated at 80° C. for 72 h. A white precipitate was present. The mixture was filtered and the white solid was washed with EtOAc (2×1 mL) and dried in vacuo to afford the title compound as a white solid. MS (ESI, positive ion) m/z: 174, 176 (M+H).
