Procedure

In 5 ml of ethanol and 1.5 ml of tetrahydrofuran were dissolved 120 mg (0.35 mmol) of 5-[2-(8-methoxy-2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizine-9-yl)vinyl]thiophene-2-carboaldehyde and 123 mg (0.39 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred with heating at 60° C. for 3 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 ethanol to give 100 mg of a dark brown crystal (yield: 44.4%; mp: 156-160° C.)
