Procedure

A mixture of ethyl 3-(2-tert-butoxy-2-oxoethoxy)-6-((2,4-dichlorobenzyl)oxy)-1-benzothiophene-2-carboxylate (1.1 g), 1N NaOH (5 mL), EtOH (5 mL) and THF (10 mL) was stirred at 50° C. for 24 h. Water and 1N HCl (5 mL) were added to the mixture and the mixture was extracted with THF-EtOAc. The organic layer was washed with brine, dried over MgSO4 and concentrated in vacuo. The residue was washed with hexane to give the title compound (0.850 g). The obtained crystals were recrystallized from acetone-water.
