実験手順

2-[(4-{2-[(5-Bromopyridin-2-yl)(heptyl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester (1.72 g) synthesized in Example 293-1 was dissolved in dioxane (5 mL), 4 mol/L hydrochloric acid-dioxane (25 mL) was added, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was concentrated under reduced pressure, azeotroped with diethyl ether, and the precipitated solid was collected by filtration to give the title compound (1.0 g) as a white solid.
