実験手順

2-{[4-(2-{[5-(4-Fluorophenyl)pyridin-2-yl]oxy}ethyl)-1,3-thiazol-2-yl]thio}-2-methylpropionic acid tert-butyl ester obtained in Example 100-2 was dissolved in dichloromethane (2 ml), trifluoroacetic acid (1 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=5:1 to 2:1) to give the title compound (201 mg) as a white solid.
