This mixture was reacted by heating under reflux for 4 hours, and the precipitated solid was filtered off. The filtrate was concentrated and isolated by a column chromatography of silica gel to obtain 42 mg (yield 24%) of white (+)-4-(2-methyloctanoyl) biphenyl, 4-octyloxycarbonyl benzoic acid ester having the aforementioned physical and chemical properties.
