Reaction Steps

In 4 ml of ethanol were dissolved 100 mg (0.25 mmol) of 3-[5-[2-(4-dibutylamino-2-methoxyphenyl)vinyl]thiophene-2-yl]propenal and 87 mg (0.28 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene) propanedinitrile. After the mixture was stirred with heating at 50° C. for 4 hours, the product was separated by filtration and washed with ethanol. The product was purified by silica gel column chromatography to give 97 mg of a black crystal (yield: 55.5%).
