Versuchsvorschrift

To a solution of 3-methoxymethoxy-5,5,8,8,-tetramethyl-5,6,7,8-tetrahydro-naphthalene-2-carboxylic acid (Compound K, as described in U.S. Pat. No. 5,856,490, 112mg, 0.38 mmol) in 6 ml of anhydrous methylene chloride was added 4-(dimethylamino)pyridine (DMAP, 100 mg, 0.46mmol), methyl 2,6-difluoro-4-aminobenzoate (Compound H1, as described in U.S. Pat. No. 5,856,490, 77mg, 0.38mmol ) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC, 110 mg, 0.57 mmol). The reaction mixture was stirred at room temperature for overnight then concentrated to dryness. The residue was purified by column chromatography with ethyl acetate: hexane (1:9) to yield the title compound as a clear oil.
