Reaction Steps

Benzyl 1-[1-oxo-2-[5-[2-(2H-tetrazol-5-yl)phenyl]-1-H-benzimidazole-1-yl]octyl]-2-pyrrolidinecarboxylate (0.388 mmoles, 230 mg) was dissolved in 5.0 ml methanol/3.0 ml 2N NaOH and stirred at room temperature for 16 hours. The ethanol was removed in vacuo. The aqueous layer washed with ether. The pH was adjusted to 3.5 using 2N HCl with cooling. The precipitate was filtered and dried to yield 75 mg of 1-[1-Oxo-2-[5-[2-(2H-tetrazol-5-yl)phenyl]-1H-benzimidazole-1-yl]octyl]-L-proline. (MS)
