Procedure
To a mixture of the compound (88.5 mg) obtained in Example 3, methyl iodide (15 μl) and dimethylformamide (2 ml), sodium hydride (content=60%; 10 mg) was added and the resulting mixture was stirred at room temperature for 4 days. To the reaction mixture, ethyl acetate and a saturated aqueous sodium hydrogencarbonate solution were added. The organic layer was washed with a saturated aqueous sodium chloride solution, dried with anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent, n-hexane:ethyl acetate=2:3) to give 19.3 mg of the titled compound (yield, 21%).
