In 15 ml of ethanol and 5 ml of tetrahydrofuran were dissolved 500 mg (1.37 mmol) of 4-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]benzaldehyde and 380 mg (1.50 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred at 50° C. for 9 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 320 mg of a black powder (yield: 38.9%; mp: 175-177° C.)
