실험 절차
Compound 3 (41.5 mg, 0.0999 mmol) obtained in Example 3 was dissolved in 1,4-dioxane (3.0 mL), and thionyl chloride (21.9 μL, 0.300 mmol) was added thereto at room temperature, followed by stirring for 1 hour. A saturated aqueous sodium bicarbonate solution was added to the reaction mixture, followed by extraction with ethyl acetate twice. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to yield a residue. The residue was purified by preparative thin layer chromatography to obtain the title compound (11.6 mg, 28%).
