실험 절차

2-{[4-(2-Hydroxyethyl)-1,3-thiazol-2-yl]thio}-2-methylpropionic acid tert-butyl ester (1.0 g) synthesized in Example 4 and N-(4-hydroxyphenyl)benzamide (703 mg) were dissolved in tetrahydrofuran (10 mL), triphenylphosphine (866 mg) and diethyl diazodicarboxylate (575 mg) were added thereto under ice-cooling, and the mixture was stirred at room temperature for 8 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=2:1) to give the title compound (1.1 g) as a white solid.
