Versuchsvorschrift

1-Amino-N-(4-chlorobenzyl)-6-iodo-4-oxo-1,4-dihydro-3-quinolinecarboxamide (0.25 g) from Preparation No. 57, copper (I) iodide (32 mg), and bis(triphenylphosphine)palladium (II) chloride (19 mg) are suspended in diethylamine (8 mL). Propargyl alcohol (39 μL) is added and the mixture is allowed to stir at room temperature for 16 h. The mixture is diluted with ethanol and then concentrated in vacuo. The crude solid is triturated with dichloromethane and recrystallized in acetic acid to affording 76 mg of the title compound as a beige solid.
