Versuchsvorschrift
A solution of 26.7 g (0.200 mol) of aluminium chloride and 31 g (0.200 mol) of 5-chlorovaleryl chloride in 200 ml of 1,2-dichloroethane is added slowly to a solution of 13.4 g (0.200 mol) of pyrrole in 250 ml of 1,2-dichloroethane. The reaction medium is stirred for 2 h at room temperature and is poured onto ice-cold hydrochloric acid. After extraction with methylene chloride, a red-brown oil is obtained.
