Procedure

A mixture of 3-[4-(benzyloxy)phenyl]-1-ethyl-7-(trifluoromethyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (197 mg) and 10% palladium on carbon (50% wet, 68 mg) in MeOH (6.5 mL) and EtOAc (6.5 mL) was hydrogenated under balloon pressure at room temperature for 4 h. 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 (103 mg).
