Procedure
Using the same method as in Example 19-(ii), 4-methoxybenzene boronic acid was reacted with the 2-[((2-[(5-bromo-2-methylphenyl)amino]-2-oxoethoxy)acetyl)amino]-5-chlorobenzoic acid.methyl ester obtained in Example 38-(i) to give 5-chloro-2-[((2-[(4′-methoxy-4-methylbiphenyl-3-yl)amino]-2-oxoethoxy)acetyl)amino]benzoic acid.methyl ester (yield: 84%).
