실험 절차

In 5 ml of ethanol were dissolved 149 mg (0.57 mmol) of 4-dibutylamino-2-methoxybenzaldehyde and 158 mg (0.62 mmol) of 2-(3-cyano-4,5-dimethyl-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 262 mg of a dark brown crystal (yield: 92.9%; mp: 211-213° C.)
