実験手順

15 mg (0.17 mmol) of para-formaldehyde, 15 mg (0.17 mmol) of morpholine and 3 mg (0.02 mmol) of copper iodide are added to a suspension of 47 mg (0.17 mmol) of 8-ethynyl-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in 5 ml of anhydrous dioxan, then a drop of acetic acid is added and the mixture is heated at 85° C. for 48 hours. The raw reaction product is then filtered, the filtrate is evaporated and the residue is purified by preparative LCMS to give 4 mg (6%) of 8-(3-morpholin-4-yl-prop-1-ynyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in the form of a white solid.
