Procedure
To a solution of the compound prepared in Example 46 (330 mg) in dimethylformamide (5 mL) were added potassium carbonate (252 mg) and ethyl iodide (142 mg), and the mixture was stirred for 2 hours at room temperature. To the reaction mixture was added water and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine sequentially, dried over anhydrous sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel (n-hexane:ethyl acetate=8:2) to give the title compound (210 mg) having the following physical data.
