Reaction Steps

Serine methyl ester (1.0 moles, 0.119 g), diisopropylethylamine (1.0 mmoles, 0.206 g), 2-[5-[2-(2H-tetrazol-5-yl)phenyl]-1H-benzimidazol-1-yl]octanoic acid (1.0 mmoles, 0.405 g), hydroxybenzotriazole (1.0 mole, 0.135 g), and dicyclohexylcarbodiimide (1.0 moles, 0.206 g) were reacted as in Example 37. The resulting ester (0.19 moles, 0.097 g) was hydrolyzed as in Example 37 to yield 0.052 g of N-[1-oxo-2-[5-[2-(2H-tetrazol-5-yl]phenyl]-1H-benzimidazol-1-yl]octyl]-L-serine (MS).
