Using the same method as in Example 19-(ii), 2-benzofuran boronic acid was reacted with the 2-[((2-[(3-bromophenyl)amino]-2-oxoethoxy)acetyl)amino]-5-chlorobenzoic acid.methyl ester obtained in Example 19-(i) to give 2-([(2-([3-(1-benzofuran-2-yl)phenyl]amino)-2-oxoethoxy)acetyl]amino)-5-chlorobenzoic acid.methyl ester (yield: 44%).
