Trifluoroacetic acid → 2-[(4-{3-[(3-Cyanopyridin-2-yl)(heptyl)amino]propyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid trifluoroacetate

Participants

Reaction Steps

A compound obtained using 2-{[4-(3-aminopropyl)-1,3-thiazol-2-yl]thio}-2-methylpropionic acid tert-butyl ester synthesized in Example 33 and 2-chloronicotinonitrile as starting materials and by operations similar to those of Example 265-1 and Example 265-2 was treated with dichloromethane and trifluoroacetic acid, and the mixture was stirred at room temperature for 12 hr. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; chloroform:methanol=50:1) to give the title compound.
