Versuchsvorschrift

3-Propylisoxazole-5-carboxylic acid (9 mg, 55 μmol) and HATU (20.8 mg, 55 μmol) were combined in DMF (0.2 mL) and allowed to stand at room temperature for 10 minutes. (2S,4R)-4-Amino-5-(5′-chloro-2′-fluorobiphenyl-4-yl)-2-hydroxymethyl-2-methylpentanoic acid (20 mg, 55 μmol) in DMF and DIPEA (28.6 μL, 164 μmol) were added, and the resulting mixture was stirred for 20 minutes at room temperature. The mixture was concentrated under reduced pressure and the residue was dissolved in AcOH purified by preparative HPLC to yield the title compound (0.5 mg). MS m/z [M+H]+ calc'd for C26H28ClFN2O5, 503.17. found 504.2.
