실험 절차
A mixture of 1 g of hexanal, 2.5 g of 2-(4-p-propylphenylbutyl)-propane-1,3-diol (obtainable by reacting diethyl malonate with 4-p-propylphenylbutyl bromide to give diethyl 2-(4-p-propylphenylbutyl)-malonate and reducing the latter with LiAlH4), 0.01 g of p-toluenesulfonic acid and 15 ml of toluene is boiled for 3 hours under a water separator and is cooled, washed with water and evaporated. This gives 2-pentyl-5-(4-p-propylphenylbutyl-1,3-dioxane.
