실험 절차

2-[(4-{2-[4-(Benzoylamino)phenoxy]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester (500 mg) synthesized in Example 54-1 and methyl iodide (170 mg) were dissolved in N,N-dimethylformamide (6 mL), potassium tert-butoxide (135 mg) was added, and the mixture was stirred at room temperature for 1 hr. Water was added to the reaction mixture, the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=3:1) to give the title compound (290 mg) as a colorless oil.
