Participants

Reaction Steps

A compound obtained using 2-({4-[2-(heptylamino)ethyl]-1,3-thiazol-2-yl}thio)-2-methylpropionic acid tert-butyl ester synthesized in Example 303-2 and quinoxaline-2-carboxylic acid as starting materials and by an operation similar to that of Example 312-1 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.
