실험 절차
To the resin obtained using 2-methyl-2-[(4-{2-[methyl(phenyl)amino]-2-oxoethyl}-1,3-thiazol-2-yl)thio]propionic acid resin obtained in Example 487-1 as a starting material and by an operation similar to that of Example 461-6 was added trifluoroacetic acid (2.0 mL), and the mixture was left standing as it was for 2 hr. Then the resin was removed by filtration from the reaction mixture, and the filtrate was concentrated by blowing a nitrogen gas, vacuum dried, and purified by preparative HPLC to give the title compound (30 mg) as a pale-brown oil.
