Versuchsvorschrift

To a solution of the hydroxynaphthalene (0.64 g) obtained in (2) above and triethylamine (0.3 g) in methylene chloride (40 ml) was added drop by drop the 6-(1,1,1-trifluoro-2-octyloxycarbonyl)naphthalene-2-carboxychloride (0.8 g) obtained in (1) above. To the solution was added dimethylaminopyridine (0.02 g) and the mixture was stirred at room temperature overnight. The solution was neutralized with dilute aqueous hydrochloric acid solution and extracted with methylene chloride. The extract was dried over anhydrous magnesium sulfate and distilled to remove the solvent. The residue was purified by silica-gel column chromatography (developer: hexane/ethyl actate=20/1) to obtain the titled compound (0.4 g) having specific rotation, [α]D20 =+45.5°.
