실험 절차

A mixture of 3-(benzyloxy)-1-methyl-1H-pyridin-2-one (23 g, 106.85 mmol) and 10% palladium on carbon (2.3 g) in methanol (250 mL) was stirred under 1 atmosphere of hydrogen for 5 hr at room temperature. The catalyst was removed by filtration. The filtrate was concentrated in vacuo to give the title compound (12 g (90%) as a purple solid: 1H NMR (400 MHz, DMSO) delta 8.96 (s, 1H), 7.15-7.13 (m, 1H), 6.70-6.68 (m, 1H), 6.07 (t, J=7.0 Hz, 1H), 3.47 (s, 3H).
