Versuchsvorschrift
In 5 ml of ethanol and 1.5 ml of tetrahydrofuran were dissolved 135 mg (0.40 mmol) of 5-[2-(8-methoxy-2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizine-9-yl)vinyl]thiophene-2-carboaldehyde and 110 mg (0.43 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred with heating at 60° C. for 3.5 hours. The solvent was evaporated off and the residue was washed with ethanol. The residue was purified by silica gel column chromatography and washed with methanol to give 178 mg of a dark brown crystal (yield: 78.1%; mp: 159-161° C.)
