Versuchsvorschrift

In 3 ml of ethanol and 1 ml of tetrahydrofuran were dissolved 146 mg (0.46 mmol) of 5-(4-dibutylamino-2-methoxyphenyl)-2,4-pentadienal and 101 mg (0.51 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene)propanedinitrile. To this mixture was added 36 mg of ammonium acetate, and the mixture was stirred at room temperature for 19 hours. The precipitate was separated by filtration, washed with ethanol, and purified by silica gel column chromatography to give 140 mg of a dark greenish brown crystal (yield: 60.9%; mp: 156-160° C.)
