In 5 ml of ethanol were dissolved 150 mg (0.57 mmol) of 4-dibutylamino-2-methoxybenzaldehyde and 197 mg (0.63 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. After the mixture was stirred at 50° C. for 2 hours, ethanol was evaporated off. The residue was purified by silica gel column chromatography to give 272 mg of a dark brown crystal (yield: 85.2%; mp: 191-194° C.)
