실험 절차

To a solution of 0.24 g (0.73 mmol) of 4-[(5,6,7,8-tetrahydro-8,8-dimethyl-5-oxonaphth-2-yl)ethynyl]benzoic acid (Compound 7) in 10 ml of dry CH2Cl2 was added 0.09 g (0.74 mmol) of dimethylaminopyridine, 0.115 ml (0.80 mmol) of trimethylsilylethanol and 0.17 g (0.88 mmol) of 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride. The reaction mixture was stirred at 25° C. for 5 hours, washed with sat. aqueous NaHCO3 and brine, dried over Na2SO4 and concentrated in vacuo to an oil. Purification by flash chromatography (silica, 10% EtOAc-hexane) yielded the title compound as a white solid.
