実験手順

In 12 ml of ethanol and 4 ml of tetrahydrofuran were dissolved 500 mg (0.84 mmol) of 5-[2-[4-dibutylamino-2-(tert-butyldiphenylsiloxy)phenyl]vinyl]thiophene-2-carboaldehyde and 234 mg (0.92 mmol) of 2-(3-cyano-4,5-dimethyl-5-trifluoromethyl-2(5H)-furanylidene)propanedinitrile. The mixture was stirred with heating at 60° C. for 4.5 hours. The solvent was evaporated off and the residue was washed with ethanol. The residue was purified by silica gel column chromatography and washed with ethanol to give 576 mg of a dark reddish brown crystal (yield: 82.6%; mp: 186-187° C.).
