실험 절차

215 mg of 11-amino-2-[2-(dimethylamino)ethyl]-1H-dibenzo[de,h]isoquinoline-1,3(2H)-dione (obtained in example 3) (0.645 mmole) were dissolved in 10 ml of acetonitrile. 250 mg (2 molar equivalents) of 2,1,3-benzothiadiazol-5-yl 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). 303 mg of the desired product (formula shown hereinabove) were isolated as a red powder (yield=89%) which was characterized as follows:
