Conditions

Temperature: 20 °C

Procedure

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), 7 mL of dichloromethane, 23 μL of methyl chloroformate and 41 μL of triethylamine were added. The mixture was magnetically stirred at 20° C. during 4 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 102 mg (yield: 87%) of the desired product (formula below) as an orange powder
