50 mg (0.26 mmol) of copper iodide, 69 mg (0.68 mmol) of triethylamine and 37 mg (0.05 mmol) of dichlorobis(triphenylphosphine)-palladium (11) are added to a suspension of 200 mg (0.52 mmol) of 8-iodo-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in 5 ml of anhydrous dioxan, then this mixture is degassed under argon. After 15 minutes, 65 mg (0.78 mmol) of dimethyl-prop-2-ynyl-amine are added, then the mixture is heated at 100° C. for 6 hours. The raw reaction product is then filtered on celite, the filtrate is evaporated to dryness and the residue is purified by chromatography on silica (ethyl acetate/methanol/ammonia) to give 64 mg (36%) of 8-(3-dimethylamino-prop-1-ynyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in the form of a white solid.
