실험 절차

2-Methyl-2-[(4-{2-[(methylsulfonyl)oxy]ethyl}-1,3-thiazol-2-yl)thio]propionic acid tert-butyl ester (1.0 g) synthesized in Example 5 and 1-[3-(trifluoromethyl)phenyl]-1H-pyrazole-4-ol (600 mg) were dissolved in N,N-dimethylformamide (10 mL), potassium carbonate (363 mg) was added, and the mixture was stirred at 85° C. for 3 hr. Water was added to the reaction mixture, and 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=10:1 to 4:1) to give the title compound (400 mg) as a colorless oil.
