Procedure

To a mixture of ethyl 6-((2,4-dichlorobenzyl)oxy)-3-hydroxy-1-benzothiophene-2-carboxylate (200 mg) in DMF (dry) (5.0 mL) were added K2CO3 (104 mg) and ethyl 2-bromoacetate (0.084 mL). The mixture was stirred at room temperature for 16 h. The mixture was diluted with water and extracted with EtOAc. The combined organic layer was washed successively with water and brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/hexane) to give the title compound (152.7 mg).
