Reaction Steps

In 5 ml of ethanol were dissolved 200 mg (0.46 mmol) of [3-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]-2-methoxy-5,5-dimethyl-2-cyclohexenylidene]acetaldehyde and 127 mg (0.50 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. After the mixture was stirred with heating at 60° C. for 2 hours, the solvent was evaporated off. The residue was purified by silica gel column chromatography to give 226 mg of a brown crystal (yield: 73.6%; mp: 141-151° C.)
