Basic ethers of 7-oxo-7H-benzo(c) fluorene have been shown to evidence a pronounced antineoplastic and immunosuppressive effect in mammals suffering from leukemia. The technique for preparing the described ethers and the addition salts thereof with pharmaceutically acceptable organic and inorganic acids involves the aminoalkylation of 5-hydroxy-7-oxo-7H-benzo(c) fluorene and its corresponding nuclear substituted derivatives on the hydroxylic oxygen atom.
