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 8 ml of acetonitrile. 67 μl (2 molar equivalents) of 3-pyridyl 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). 132 mg of the desired product (formula shown hereinabove) were isolated as a red powder (yield=94%) which was characterized as follows:
