Reaction Steps

207 mg (0.51 mmol) of [3-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]-5,5-dimethyl-2-cyclohexenylidene]acetaldehyde and 175 mg (0.56 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 3 hours. The precipitate was separated by filtration and washed with ethanol. The residue was purified by silica gel column chromatography to give 274 mg of a dark brown crystal (yield: 76.8%; mp: 164-166° C.).
