Procedure

A mixture of chloromethyl butyrate (6.8 μL, 54.5 μmol) and NaI (8.2 mg, 54.5 μmol) in acetone (0.5 mL, 7 mmol) was stirred at 60° C. for 1 hour, then it was added to a mixture of (R)-3-[N-(5′-chloro-2′-fluorobiphenyl-4-ylmethyl)-N′-(2-trityl-2H-tetrazole-5-carbonyl)hydrazino]-2-hydroxypropionic acid (12.3 mg, 18.2 μmol) and DIPEA (4.8 μL, 27.2 μmol) in acetone (0.5 mL). The resulting mixture was stirred at 40° C. for 2 hours, concentrated and partitioned between EtOAc (10 mL) and water (2 mL). The organic layer was dried over MgSO4, filtered, and concentrated. 4.0 M HCl in 1,4-dioxane (40.0 μL, 160 μmol) in MeCN (0.2 mL, 4 mmol) was added and the resulting mixture was stirred at room temperature for 20 minutes. The mixture was concentrated and the residue was dissolved in AcOH (1.5 mL), filtered, and purified by reverse phase preparative HPLC to yield the title compound (1.3 mg). MS m/z [M+H]+ calc'd for C23H24ClFN6O6, 535.14. found 535.1.
