HATU (37.9 mg, 99.6 μmol) was added to a solution of 1-hydroxy-1H-1,2,3-benzotriazole-6-carboxylic acid (14.9 mg, 83 μmol) in DMF (0.5 mL, 6.4 mmol) and the resulting mixture was stirred at room temperature for 5 minutes. (2R,4R)-4-Amino-5-(3′-chlorobiphenyl-4-yl)-2-hydroxypentanoic acid 2,2,3,3,3-pentafluoropropyl ester (30.0 mg, 66.4 μmol) was added to the mixture, followed by DIPEA (35 μL, 0.2 mmol) dropwise over 5 minutes, and the mixture was stirred at room temperature for 30 minutes. The mixture was concentrated in vacuo to yield a yellow liquid, which was purified by preparative HPLC to yield the title compound as a white solid (2.9 mg, purity 100%). MS m/z [M+H]+ calc'd for C27H22ClF5N4O5, 613.12. found 613.0.
