Using the same method as in Example 19-(ii), 2,6-dimethoxy-3-pyridine 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 5-chloro-2-([(2-([3-(2,6-dimethoxypyridin-3-yl)phenyl]amino)-2-oxoethoxy)acetyl]amino)benzoic acid.methyl ester (yield: 51%).
