A reaction analogous to that used for the synthesis of 3-hydroxy-1,2-dimethyl-4- pyridinone was employed, starting with ethanolamine (0.44 g). No precipitate was observed after concentration. Recrystallization from ethanol and diethyl ether resulted in a white powder (0.53 g). Proton NMR (D20): 7.82 (d, 1H), 6.89 (d, 1H), 4.27 (t, 2H), 3.74 (t, 2H), 2.36 (s, 3H).
