Procedure

To a solution of the compound 72 (980 mg) in dimethylformamide (3.00 mL) was added n-butyl iodide (570 μL) at room temperature and then thereto was added potassium carbonate (691 mg) at 0° C. The solution was stirred at room temperature overnight. Water was added to the reaction solution, which was extracted with ethyl acetate. The organic layer was washed water and brine, dried over anhydrous sodium sulfate and concentrated. The organic residue was purified by column chromatography on silica gel (n-hexane:ethyl acetate=78:22→50:50) to give the title compound (960 mg) having the following physical data.
