実験手順

To 5 ml of ethanol were added 130 mg (0.41 mmol) of 5-(4-dibutylamino-2-methoxyphenyl)-2,4-pentadienal and 115 mg (0.45 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene) propanedinitrile, and the mixture was stirred with heating at 50° C. for 2 hours. The precipitate was separated by filtration and purified by silica gel column chromatography to give 187 mg of a greenish brown crystal (yield: 82.5%; mp: 168-172° C.)
