Ethyl 3-(4-cyanophenyl)3-oxopropanoate (64 mg, 0.3 mmol) was heated with DMFDMA (50 μl) and dry THF (1 ml) at 70° C. for 3 hours. The cooled mixture was then added to a suspension of amino[2-(2-quinolylamino)ethyl]carboxamidinium 4-methylbenzenesulfonate (prepared according to Example 12), (120 mg, 0.3 mmol) in ethanol (2 ml) containing 0.35 mmol of sodium ethoxide. The reaction was then heated at 80° C. overnight and then concentrated in vacuo. The residue was taken up in dichloromethane and washed with saturated aqueous sodium bicarbonate. The organic layer was concentrated in vacuo. The residue was taken up in acetonitrile. Addition of water gave a precipitate which was filtered off and dried to give the title compound.
