Reaction Steps

In 5 ml of ethanol were dissolved 130 mg (0.45 mmol) of 3-(4-dibutylamino-2-methoxyphenyl)propenal and 156 mg (0.50 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. After the mixture was stirred with heating at 50° C. for 2 hours, the solvent was evaporated off. The residue was purified by silica gel column chromatography to give 229 mg of a dark greenish brown crystal (yield: 86.9%; mp: 190-192° C.)
