실험 절차
Under an argon atmosphere, to a suspension of 4-(N-(4-(4-(4-cyclohexylbenzyloxy)phenyl)-2-thiazolyl)-N-methylaminomethyl)benzoic acid (30.0 g, 58.5 mmol) obtained in Example 2(5) was added 1N aqueous potassium hydroxide solution (56.0 ml) at 50° C. and the mixture was heated under reflux for 40 min. After stirring at room temperature for 45 min., the crystals were collected by filtration, washed with a tetrahydrofuran-ethanol mixed solvent (3:1, 150 ml) and ethanol (210 ml), and dried to give the title compound (28.0 g, yield 90.9%).
