Versuchsvorschrift

10.06 parts of 1-(4'-fluorophenacyl)-pyridinium chloride and 10.76 parts of 1-(4-fluorophenyl)-3-(4'-dimethylaminophenyl)-1-oxoprop-2-ene are heated at 130° C. for 81/2 hours together with 34 parts of ammonium acetate in 50 parts of glacial acetic acid. The mixture is stirred for 17 hours at room temperature, after which the precipitated colorless crystals are filtered off under suction, washed with methanol and water and dried at 60° C. in a drying oven to give 10.5 parts of 4-(4-dimethylamino-phenyl)-2,6-bis-(4'-fluorophenyl)-pyridine, which dissolves in glacial acetic acid to give an orange yellow coloration (λmax: 431 nm).
