Procedure

The compound obtained in Example 2-1 step (v) was dissolved in dimethylformamide (50 ml), and potassium carbonate (3.52 g) and methyl 2-(2-bromoethoxy)benzoate (2.2 g) were added thereto. The mixture was stirred at room temperature for 96 hours and partitioned between ethyl acetate and 2M hydrochloric acid. The organic layer was dried and concentrated under reduced pressure. The residue was dissolved in methanol and purified by RPHPLC to give the titled compound. Yield: 0.768 g (22%).
