実験手順
4-Hydroxy-6-methyl-1H-pyridin-2-one (25 g, 0.2 mol) and N-chlorosuccinimide (29.4 g, 0.22 mol) were dissolved in 200 mL of acetic acid. The reaction was heated at 115° C. for 6 hours. The reaction was cooled to room temperature, the solid was filtered, and washed with acetic acid and hexanes. The solid was dried in a vacuum oven overnight to give a white solid (19.2 g, 60%): 1H NMR (300 MHz, DMSO-d6) δ 11.46 (br s, 1H), 11.04 (s, 1H), 5.79 (s, 1H), 2.09 (s, 3H).
