Reaction Steps

2-[(4-{2-[(5-Ethylpyrimidin-2-yl)(4-pyridin-3-ylbenzyl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester synthesized in Example 407-1 was treated with dichloromethane and trifluoroacetic acid. The reaction solution was concentrated under reduced pressure, and the residue was purified by high performance liquid chromatography (elution solvent; 0.05% trifluoroacetic acid-water:0.05% trifluoroacetic acid-acetonitrile=75:25 to 30:70) to give the title compound.
