A mixture of 3-hydroxy-1-methyl-1H-pyridin-2-one (11.5 g, 91.91 mmol) and Ru/Al2O3 (2.5 g) in methanol (120 mL) was stirred under hydrogen (10 bar) in a 250-mL pressure reactor for 48 hr at 50° C. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give the title compound (11.3 g, 90%) as a brown oil: 1H NMR (400 MHz, DMSO delta 3.85-3.82 (m, 1H), 3.28-3.18 (m, 2H), 2.79 (s, 3H), 1.98-1.92 (m, 1H), 1.87-1.81 (m, 1H), 1.75-1.69 (m, 1H), 1.64-1.55 (m, 1H).
