Procedure

[4-[(2S)-2-Benzenesulfonylamino-2-(4-phenyl-butylcarbamoyl)-ethyl]-2-(benzyloxycarbonyl-methyl-amino)-phenoxy]-fluoro-acetic acid ethyl ester of Step C is dissolved in EtOH (2 mL) and 1N KOH (0.32 mL) is added. The mixture is stirred overnight. The solution is concentrated, and suspended in ETOAC and loaded on silica gel plug. The plug is washed with ETOAC (100 mL) to remove the impurities. The product is eluted from the plug by using 2% HOAC in ETOAC. The filtrate is concentrated to provide [4-[(2S)-2-benzenesulfonylamino-2-(4-phenyl-butylcarbamoyl)-ethyl]-2-(benzyloxycarbonyl-methyl-amino)-phenoxy]-fluoro-acetic acid.
