Versuchsvorschrift
10 mL (137 mmol) of sulphinyl chloride are added to 1.05 g (3.78 mmol) of 3-carboxy-4-cyclopropyl-1-(quinolin-4-yl)-1H-pyrrole dissolved in 20 mL of chloroform at a temperature in the region of 20° C. under an argon atmosphere. After stirring for one hour at the reflux temperature of the solvent, the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa). The residue is dissolved in 20 mL of chloroform and then concentrated to dryness again, giving 1.12 g (3.78 mmol) of 3-chlorocarbonyl-4-cyclopropyl-1-(quinolin-4-yl)-1H-pyrrole in the form of a yellow solid, which is used directly in the following step.
