Reaktionsschritte

A solution of 5,5-dimethyl-5,6-dihydro-8-(2-thienyl)-naphthalene-2-carboxylic acid (Compound E6, 79.0 mg, 0.280 mmol), 2-trimethylsilylethyl 4-hydroxybenzoate (73.3 mg, 0.308 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (70.0 mg, 0.364 mmol), and 4-N,N-dimethylaminopyridine (44.5 mg, 0.364 mmol) in 2.0 mL DMF was stirred overnight at room temperature. Et2O (100 mL) was added and the solution washed with H2O, 5% HCl, saturated aqueous NaCO3, and saturated aqueous NaCl before being dried over MgSO4. Removal of the solvents under reduced pressure and column chromatography (10% EtOAc-hexanes) of the residual oil afforded the title compound as a colorless solid.
