Abstract Derivatives of 9-aminoacridine, namely N-[ψ-(acridin-9-ylamino) alkyl]-3- (trimethylstannyl) benzamides (1), where the alkyl group is propyl (1a) and octyl (1b), and 2- (acridin-9-ylamino)-3-(4-hydroxyphenyl) propionic acid (2), have been synthesized with the aim to use them as precursors in the syntheses of radiolabeled DNA intercalators for biological experiments. It was observed that compounds 1a and 1b can exist in two ...
