{4-[3,3-Bis-(4-bromo-phenyl)-2-ethoxy-allylsulfanyl]-2-methyl-phenoxy}-acetic acid methyl ester (170 mg, 0.3 mmol, example 25) was dissolved in ethanol (5 ml). 1N NaOH (3 ml, 3 mmol) was added at room temperature and the reaction mixture was stirred for 30 min at room temperature, after which it was treated with 1N HCl (15 ml) and extracted with ethyl acetate (2×20 ml). The combined organic phases were dried and evaporated to give the title compound in 150 mg (90%) yield.
