Reaction Conditions

Reaction Steps

0.5 mL (5.73 mmol) of oxalyl chloride is added to a solution, cooled to a temperature in the region of 5° C., of 0.42 g (1.76 mmol) of 3-carboxy-1-(quinol-5-yl)-1H-pyrrole in 10 mL of dichloromethane under an argon atmosphere. After stirring at a temperature in the region of 22° C. for 15 hours, concentrating the reaction mixture to dryness under reduced pressure (2.7 kPa) gives 0.55 g of 3-chlorocarbonyl-1-(quinol-5-yl)-1H-pyrrole hydrochloride in the form of a cream-coloured solid which is used directly in the following step.
