実験手順

In an ethanol/tetrahydrofuran mixed solvent were dissolved 180 mg (0.54 mmol) of 4-[2-(4-dibutylaminophenyl)vinyl]benzaldehyde and 118 mg (0.59 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene]propanedinitrile. To this mixture, 46 mg (0.60 mmol) of ammonium acetate was added, and the mixture was stirred at room temperature. The solvent was evaporated off. The residue was purified by silica gel column chromatography and washed with ethanol to give 245 mg of a black crystal having a mp of 224-226° C. (yield: 88.4%).
