실험 절차

A solution of 5,5-dimethyl-5,6-dihydro-8-(2-thienyl)-naphthalene-2-carboxylic acid (Compound E6, 50.0 mg, 0.177 mmol), ethyl 4-hydroxybenzoate (38.2 mg, 0.230 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (44.0 mg, 0.230 mmol), and 4-N,N-dimethylaminopyridine (28.0 mg, 0.230 mmol) in 2.0 mL DMF was stirred overnight at room temperature. EtOAc (50 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 sovents under reduced pressure and column chromatography (10% EtOAc-hexanes) of the residual oil afforded the title compound as a colorless solid.
