実験手順

0.75 g of optically active 1-butyryloxy-2-propanol [obtainable by esterification of (S)-1,2-propanediol], 1,7 g of p-(p-n-octylphenyl)-benzoic acid chloride, 20 ml of toluene and 2,1 ml of pyridine are boiled under reflux for 6 hours. The pyridinium chloride is filtered off hot with suction and the filtrate is worked up in the customary manner. Optically active 1-butyryloxy-2-[p-(p-n-octylphenyl)-benzoyloxy]-propane is obtained.
