実験手順
In 9 ml of ethanol and 3 ml of tetrahydrofuran were dissolved 440 mg (1.12 mmol) of 4-[2-(4-dibutylamino-2-methoxyphenyl) vinyl]-2,5-dimethylbenzaldehyde and 310 mg (1.22 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. After the mixture was stirred at 70° C. for 6 hours, the solvent was evaporated off. The residue was purified by silica gel column chromatography and washed with ethanol to give 522 mg of a black powder (yield: 74.3%; mp: 205-207° C.)
