Reaction Steps

In 6 ml of ethanol were dissolved 173 mg (0.42 mmol) of [3-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]-5,5-dimethyl-2-cyclohexenylidene]acetaldehyde and 95 mg (0.48 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene) propanedinitrile. To this mixture was added 34 mg of ammonium acetate, and the mixture was stirred with heating at 50° C. for 3.5 hours. The solvent was evaporated off and the residue was purified by silica gel column chromatography to give 229 mg of a dark brown crystal (yield: 91.8%; mp: 228-230° C.)
