Versuchsvorschrift
28 mg (<5 mol %) of zinc(II) chloride and 4.4 g (61.5 mmol) of pyrrolidine are added in succession to a mixture of 1.1 g (4.1 mmol) of 4′-chloro-[2,2′;6′,2″]terpyridine in 15 ml of 2-methyl-2-butanol. The mixture is heated at reflux for 20 hours, cooled and filtered. After recrystallisation from toluene, pure 4′-pyrrolidin-1-yl-[2,2′;6′,2″]terpyridine is obtained in the form of a white solid. MS (EI, 70 eV): m/z=303 (15); 302 (90, [M+]); 273 (100); 233 (25).
