実験手順

A mixture of 2-methyl-6-phenyl-hexa-3,5-diyn-2-ol (3.8 g, 20.6 mmol) sodium hydride (60%, 83 mg, 2.06 mmol) and toluene (20 ml) was stirred at reflux for 1 hour. The mixture was evaporated. Chromatography on silica gel with petroleum and ethyl acetate (3:1), gave the title compound. Yield 0.54 g (21%).
