Reaction Steps

To 5 ml of ethanol were added 100 mg (0.32 mmol) of 5-(4-dibutylamino-2-methoxyphenyl)-2,4-pentadienal and 110 mg (0.35 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile, and the mixture was stirred with heating at 50° C. for 2.5 hours. The precipitate was separated by filtration and purified by silica gel column chromatography to give 173 mg of a yellowish brown crystal (yield: 89.1%; mp: 208-210° C.)
