Reaction Steps

To a solution of tert-butyl 3-(6-(4-(tert-butoxycarbonylamino)piperidin-1-yl)pyrazin-2-yl)-5-nitro-1H-indole-1-carboxylate (200 mg, 0.37 mmol) in MeOH (2 mL) was added Raney Ni (30 mg) and then heated at 50° C. for 5 min. Hydrazine hydrate (0.2 mL) was added and the resulting mixture was stirred at the same temperature for another 10 min. The reaction mixture was cooled to RT and filtered off the Raney Ni through Celite. The filtrate was concentrated to obtain the title compound as a pale brown solid (160 mg, 85%). MS (ESI, pos. ion) m/z: 509.3 (M+1).
