참여 물질

반응 단계

7-Nitro-4H-benzo[1,4]oxazin-3-one (0.65 g, 3.3 mmol) and 10% palladium on carbon (0.13 g) were combined in EtOAc (15 mL) and MeOH (15 mL) and hydrogenated for 2 h at atmospheric pressure. The catalyst was removed by filtration through celite and the filtrate reduced in vacuo to yield the title compound as a colourless oil (0.50 g, 91%). δH (DMSO-d6) 4.42 (2H, s), 4.89 (2H, br s), 6.13-6.20 (2H, m), 6.56 (1H, d, J 8.1 Hz), 10.27 (1H, br s).
