A solution of 100 mg (0.30 mmole) of 11-amino-2-[2-(dimethylamino)ethyl]-1H-dibenzo[de,h]isoquinoline-1,3(2H)-dione (obtained in example 3) in 7 mL of dichloromethane was magnetically stirred at 20° C. 113 μL (2 molar equivalents) of 4-chlorophenylacetyl chloride were added. The mixture was magnetically stirred at room temperature during 3 hours. The solvent was then evaporated under reduced pressure and the residue was submitted to a flash chromatography on silica (eluent: CH2Cl2/methanol in a 97:3 volume ratio) to provide 122 mg (yield: 84%). of the desired product (formula above) as an orange powder which was characterized as follows:
