To a solution of the 4-n-decanoyloxybenzoic acid (0.43 g) obtained in Example 12, (3) and the 1,1,1-trifluoro-2-octyl 4-hydroxybenzoate (0.4 g) obtained in (2) above in tetrahydrofuran (about 30 ml) were added dicyclohexylcarbodiimide (0.32 g) and dimethylamonopyridine (0.01 g). The mixture was stirred at room temperature for about 20 hours and was distilled to remove the solvent. The residue was dissolved in dichloromethane and washed with water. The organic layer was dried over anhydrous magnesium sulfate and was distilled to remove the solvent. The residue was purified by silica-gel column chromatography (developer : hexane/ ethyl acetate=20/1) to obtain the titled compound (0.20 g).
