반응 단계
A mixture of 3-[4-(benzyloxy)phenyl]-1-ethyl-6-methoxy-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (120 mg) and 10% palladium on carbon (40 mg) in MeOH (10 mL) was hydrogenated under balloon pressure at room temperature for 2 h. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give 1-ethyl-3-(4-hydroxyphenyl)-6-methoxy-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (75 mg) as white crystals.
