실험 절차

The thus-obtained diacetylene derivative represented by the formula (IX) is then dissolved in benzene and refluxed while being heated for 30 min. to 1 hour in the presence of potassium hydroxide. After the reaction has been completed, the reaction mixture is filtered, and the solvent is then evaporated. The residure is then purified by silica-gel column chromatography to obtain a phenylbutadiyne derivative represented by the formula (X).
