Reaction Steps

2-Methyl-2-({4-[2-({5-[4-(trifluoromethoxy)phenyl]pyrimidin-2-yl}oxy)ethyl]-1,3-thiazol-2-yl}thio)propionic acid tert-butyl ester (600 mg) obtained in Example 110-2 was dissolved in dichloromethane (6 mL), trifluoroacetic acid (2 mL) was added, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=1:1 to 0:1) to give the title compound (350 mg) as a white solid.
