100 mg of 11-amino-2-[2-(dimethylamino)ethyl]-1H-dibenzo[de,h]isoquinoline-1,3(2H)-dione (obtained in example 3) (0.30 mmole) were dissolved in 6 ml of acetonitrile. 52 μl (2 molar equivalents) of ethyl isothiocyanate was added and the reaction mixture was maintained at room temperature for 16 hours. The solvent was then evaporated under reduced pressure and the residue was submitted to a flash chromatography (SiO2, CH2Cl2/MeOH 95/5). 92 mg of the desired product (formula shown hereinabove) were isolated as a red powder (yield=73%) which was characterized as follows:
