Reaction Steps

A mixture of 8-amino-7-nitro-5H-phenanthridin-6-one (412 mg, 1.62 mmol), Pd/C (10 wt %, 234 mg) in TFA was hydrogenated at 50 psi for 50 min. The catalyst was filtered through a plug of diatomaceous earth and rinsed with ethanol. The solvent was evaporated to obtain 7,8-diamino-5H-phenanthridin-6-one trifluoroacetate salt (520 mg, 71%).
