Reaction Steps

In 5 ml of ethanol were dissolved 170 mg (0.65 mmol) of 4-dibutylamino-2-methoxybenzaldehyde and 141 mg (0.71 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene) propanedinitrile. To this mixture was added 50 mg of ammonium acetate, and the mixture was stirred at 50° C. for 4 hours. Ethanol was evaporated off and the residue was purified by silica gel column chromatography to give 273 mg of a dark brown crystal (yield: 95.1%; mp: 222-226° C.)
