A mixture of 3-[4-(benzyloxy)phenyl]-1-(1-methylethyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (1.5 g) and 10% Pd—C (0.444 g) in EtOH (40 ml) was hydrogenated under balloon pressure at room temperature for 5 h. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give 3-(4-hydroxyphenyl)-1-(1-methylethyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (670 mg) as a light brown solid.
