실험 절차

In 5 ml of ethanol were dissolved 170 mg (0.59 mmol) of 3-(4-dibutylamino-2-methoxyphenyl)propenal and 129 mg (0.65 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene) propanedinitrile. To this mixture was added 46 mg of ammonium acetate, and the mixture was stirred with heating at 50° C. for 2 hours. The solvent was evaporated off and the residue was purified by silica gel column chromatography to give 206 mg of a dark greenish brown crystal (yield: 74.5%; mp: 181-184° C.)
