Participants

Reaction Steps

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 185 mg (0.93 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene)propanedinitrile. To this mixture was added 65 mg of ammonium acetate, and the mixture was stirred at room temperature for 47 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 369 mg of a dark greenish brown crystal (yield: 56.6%; mp: 218-219° C.).
