Procedure

A mixture of 3-[4-(benzyloxy)phenyl]-6-methyl-1-(1-methylethyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (283 mg) and 10% palladium on carbon (50% wet) (87 mg) in MeOH (4.2 mL) and EtOAc (4.2 mL) was hydrogenated under balloon pressure at room temperature overnight. The solid was filtrated and washed with MeOH (10 mL) to remove the catalyst. The filtrate was concentrated in vacuo to give the title compound (210 mg) as a gray solid.
