Versuchsvorschrift
20 cm3 of sulphinyl chloride and one drop of dimethylformamide are added at a temperature in the region of 20° C. under an argon atmosphere to 1.39 g (4.53 mmol) of 3-carboxy-6-fluoro-1-(quinol-4-yl)-1H-indole. After stirring at reflux for 1 hour, the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa) to give 1.7 g of 3-chlorocarbonyl-6-fluoro-1-(quinol-4-yl)-1H-indole in the form of a cream solid which is used directly in the following step.
