Participants

Reaction Steps

A compound obtained using 2-[(4-{2-[(5-bromopyrimidin-2-yl)(heptyl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester synthesized in Example 442-1 and dimethylamine hydrochloride as starting materials and by an operation similar to that of Example 442-2 (solvent was changed to tert-butanol) was treated with dichloromethane and trifluoroacetic acid. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; chloroform:methanol=10:1) to give the title compound.
