Reaction Steps

To a solution of 1-[(3R)-1-(5-nitro-2-pyridinyl)-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (19.3 mg) in ethanol (3 mL), tetrahydrofuran (1 mL), and water (0.15 mL) was added 10% Pd—C (50% wet, 10 mg) and ammonium formate (32 mg). After stirring for 50 minutes at 75° C., catalyst was removed by filtration, and solvent was also removed under reduced pressure. The residue was dissolved in EtOAc, washed with saturated aqueous sodium hydrogencarbonate, and brine, dried over MgSO4, evaporated in vacuo. The residue was purified by silica gel column chromatography (chloroform:methanol=10:1 to 8:1) to give 1-[(3R)-1-(5-amino-2-pyridinyl)-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (8.5 mg) as a pale brown crystals.
