Procedure

Into a flask were charged 96.2 mg (0.28 mmol) of 4-tetradecanoyloxy benzoic acid, 78.0 mg (0.25 mmol) of 4-hydroxy-4'-(2-methyloctanoyl) biphenyl, 63.5 mg (0.31 mmol) of dicyclohexylcarbodiimide, 3.5 mg (0.03 mmol) of 4-dimethylamino pyridine and 5 ml of dried dichloromethane, which was heated under reflux for 7 hours. After the cooling, the resulting solid was filtered off and washed with dichloromethane. The organic phase was washed with 0.1 normal hydrochloric acid and further with water, dried on anhydrous magnesium sulfate, and the solvent was distilled off. This product was recrystallized with ethanol to obtain 63.5 mg (yield 40%) of white 4-tetradecanoyloxy benzoic acid-4-(2-methyloctanoyl) biphenyl.
