Reaction Steps

In 15 ml of ethanol and 5 ml of tetrahydrofuran were dissolved 540 mg (1.48 mmol) of 4-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]benzaldehyde and 500 mg (1.59 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred at 50° C. for 4 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 160 mg of a black powder (yield: 17.7%; mp: 176-178° C.)
