실험 절차

In 5 ml of ethanol were dissolved 200 mg (0.41 mmol) of 2-(tert-butyldiphenylsiloxy)-4-dibutylaminobenzaldehyde and mg (0.45 mmol) of 2-(3-cyano-4,5,5-trimethyl-2(5H)-furanylidene)propanedinitrile. After the mixture was stirred with heating at 60° C. for 3 hours, the precipitate was separated by filtration and washed with methanol. The crystal was purified by silica gel column chromatography and washed with methanol to give 199 mg of a dark brown crystal having a mp of 220-221° C. (yield: 72.6%).
