Reaction Steps

3-phthalimido-6-nitro-1,2,3,4-tetrahydrocarbazole (4.00 g) was dissolved in hot ethyl acetate (130 ml). To the cooled solution was added raney nickel, and the mixture was hydrogenated at an initial pressure of 39 psi at room temperature for 4 hr. After filtering off the insoluble materials, the filtrate was evaporated to dryness, and extracted twice into 20% aqueous methanol and the extracts combined and reduced in volume to give 3-phthalimido-6-amino-1,2,3,4-tetrahydrocarbazole (0.31 g).
