실험 절차

To a solution of (5-{1-ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butoxy)-3-methyl-phenyl]-propyl}-3-methyl-thiophene-2-sulfonylamine)-acetic acid methyl ester (210 mg, 0.4 mmol) in dioxane (10 ml) is added 2N LiOH/H20 solution (10 ml) and stirred at RT overnight. The reaction is concentrated and partitioned between EtOAc/1N HCl. The organic layer is concentrated to give the title compound (180 mg, 88%).
