실험 절차

Diethyl phenylmalonate is reduced with lithium aluminium hydride to give 2-phenyl-propane-1,3-diol and esterified with an equimolar amount of benzenesulphochloride in anhydrous pyridine to give 2-phenylpropane-1,3-diol monobenzenesulphonate (wax-like substance). Reaction thereof with the potassium salt of hexadecanethiol in ethanol gives the desired 3-hexadecylthio-2-phenylpropan-1-ol (wax-like substance).
