To a suspension of (E)-N,N-dimethyl-2-(4-nitro-1-oxidopyridin-3-yl)ethenamine (400 mg, Step c) in methanol was added palladium on carbon (50 mg, 10% wet) and the reaction mixture was stirred under hydrogen atmosphere for 2 hours. The reaction mixture was filtered through celite and the filtrate was concentrated to get 1H-pyrrolo[3,2-c]pyridine (98 mg, 44%) as off-white solid.
