Versuchsvorschrift
30 cm3 of sulphinyl chloride and one drop of dimethylformamide are added, at a temperature in the region of 22° C. and under an argon atmosphere, to 2.4 g (7.52 mmol) of 3-carboxy-6-methoxy-1-(quinol-4-yl)-1H-indole. After stirring at reflux for 16 hours, the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa) to give 2.5 g of 3-chlorocarbonyl-6-methoxy-1-(quinol-4-yl)-1H-indole in the form of a yellow solid which is used directly in the following step.
