Reaction Steps

118 mg (0.25 mmol) of [2-butyl-3-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]-5,5-dimethyl-2-cyclohexenylidene]acetaldehyde and 90 mg (0.29 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene]propanedinitrile were dissolved, and the mixture was stirred with heating at 50° C. for 40 minutes. The solvent was evaporated off. The residue was purified by silica gel column chromatography and washed with methanol to give 133 mg of a black crystal having a mp of 109-113° C. (yield: 68.9%).
