実験手順

The starting material 3-cycloundecylpropan-1-ol is obtained as follows: hydroxymethylcycloundecane is reacted with thionyl chloride to give chloromethylcycloundecane, which is reacted with malonic acid diethyl ester in the presence of sodium ethylate to give (cycloundecylmethyl)-malonic acid diethyl ester, which, after saponifying the ester group and decarboxylating the corresponding malonic acid, gives 3-cycloundecylpropionic acid. 3-Cycloundecylpropionic acid is reduced with lithium aluminum hydride in tetrahydrofuran to give 3-cycloundecylpropanol.
