PROCEDURE

实验过程

The title compound was prepared from the crude amine mixture of (1S)-N-(5-amino-1-hydroxymethyl-pentyl)-N-isobutyl-3-amino-4-fluoro-benzenesulfonamide which is described earlier (example 53, step C) and (2S)-2-tert-butoxycarbonylamino-3,3-diphenyl-propionic acid using general procedure A. The crude residue was purified by semi-preparative HPLC in several batches of 80 mg using a gradient of 50 to 80% of acetonitrile over 30 min and a flow rate of 15 mL/min, retention time=20.2 min. All the pure fractions were combined to provide 630 mg (46% yield) of the title compound.
