실험 절차

In 6 ml of ethanol and 2 ml of tetrahydrofuran were dissolved 250 mg (0.64 mmol) of 4-[2-(4-dibutylamino-2-methoxyphenyl) vinyl]-2,5-dimethylbenzaldehyde and 140 mg (0.70 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene) propanedinitrile. To this mixture was added 49 mg of ammonium acetate, and the mixture was stirred at 70° C. for 4 hours. The solvent was evaporated off, and the residue was purified by silica gel column chromatography and washed with ethanol to give 205 mg of a black powder (yield: 56.2%; mp: 242-244° C.)
