Versuchsvorschrift

To a solution of the 1,1,1-trifluoro-2-decyl-6-hydroxynaphthalene-2-carboxylate (0.5 g) obtained in (1) above, the 4-n-octyloxybenzoic acid (0.4 g) obtained in (2) above in tetrahydrofuran (40 ml) were added dicyclohexylcarbodiimide (0.45 g) and dimethylaminopyridine (0.05 g). The solution was stirred at room temperature overnight. The solution was distilled to remove the solvent. The residue was dissolved in dichloromethane (50 ml) and the solution was washed with dilute aqueous hydrochloric acid solution and water in this order. The organic layer collected was dried over anhydrous magnesium sulfate, and 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 (0.39 g) having specific rotation, [α]DD20 =+45.79°.
