A mixture of 0.5 g of 7-phenylheptanol, 0.27 g of propiolic acid, 0.005 g of p-toluenesulfonic acid and 25 ml of benzene was refluxed with stirring for six hours while water formed was removed by a Dean-Stark water separator. After the reaction was completed, the reaction solution was washed successively with a 5% aqueous sodium bicarbonate solution and a saturated sodium chloride solution, and dried over anhydrous magnesium sulfate. After removal of the solvent under reduced pressure, the obtained residue was subjected to silicagel column chromatography to yield 0.368 g of 7-phenylheptyl propiolate (compound 3).
