실험 절차
2-[(4-{2-[Heptyl(4-nitrophenyl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester (200 mg) obtained in Example 303-3 was dissolved in dichloromethane (5 mL), trifluoroacetic acid (5 mL) was added, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was concentrated under reduced pressure, and hexane was added to the residue to give the title compound (108 mg) as a pale-yellow solid.
