Procedure
A mixture of 1-(4-nitrophenyl)-2,3-dihydro-1H-imidazo[2′,1′:2,3]imidazo[4,5-b]pyridine (1.7 g) and 10% palladium on carbon (50% wet, 1.0 g) in MeOH (150 mL) was hydrogenated under balloon pressure at room temperature for 1 day. The catalyst was removed by filtration and the filtrate was concentrated under reduced pressure to give the title compound (1.2 g).
