実験手順

To a stirred solution of 3-acetyl-1H-pyrazole-5-carboxylic acid (50.9 mg, 330 μmol), HATU (125 mg, 330 μmol), and DIPEA (104 μL, 0.6 mmol) in DMF (0.6 mL, 7.7 mmol), was added (2R,4R)-4-amino-5-(3′-chlorobiphenyl-4-yl)-2-hydroxypentanoic acid ethyl ester (104 mg, 300 μmol). The resulting mixture was stirred at room temperature until the reaction was complete. The mixture was diluted with DCM and washed with saturated aqueous NaHCO3. The organics were dried over Na2SO4, and the solvent removed. Half of material was then purified by preparative HPLC to yield the title compound (20 mg) as a TFA salt. MS m/z [M+H]+ calc'd for C25H26ClN3O5, 484.16. found 484.1.
