実験手順

To a cold (0° C.) solution of 130 mg (0.35 mmol) of ethyl-6-[5,6,7,8-tetrahydro-5,5-dimethyl-8-(hydroxy)-naphth-7-yl]naphth-2-oate (Compound B4) in 2.0 mL of methylene chloride was added 50 mg (0.15 mL, 0.86 mmol) of Hunig's base, followed by 0.21 g (0.20 mL, 2.6 mmol) chloromethyl methyl ether was added and stirred at room temperature for 14 h. About 500 mgs of t-butylammonium iodide was then added and the reaction was warmed to 35° C. for one additional hour. The reaction was diluted with water, and extracted with CH2Cl2 (2×). The combined organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo to give an oil. The title compound was obtained as an oil after flash chromatography (silica, 10% ethyl acetate).
