実験手順

In 15 ml of ethanol and 5 ml of tetrahydrofuran were dissolved 730 mg (1.63 mmol) of 5-[2-(2-benzyloxy-4-dibutylaminophenyl)vinyl]thiophene-2-carboaldehyde and 573 mg (1.82 mmol) of 2-(3-cyano-4-methyl-5-phenyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred at room temperature for 21 hours and further stirred with heating at 50° C. for 3 hours. The solvent was evaporated off and the residue was washed with ethanol to give 1.15 g of a dark reddish brown crystal (yield: 94.7%; mp: 196-197° C.)
