Procedure
To a solution of (S)-methyl 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-1-((S)-1-(N-methylcyclopropanesulfonamido)butan-2-yl)-2-oxopiperidin-3-yl)propanoate (0.041 g, 0.067 mmol) from Step B above in MeOH/THF/H2O (1 mL/1 mL/2 mL) was added lithium hydroxide (8.02 mg, 0.335 mmol). The mixture was heated to 60° C. for 14 h. The reaction mixture was acidified with 1N HCl and extracted with EtOAc (×2). The organics were pooled, washed with sat. aq. NaCl solution, dried (MgSO4), filtered and the filtrate was concentrated under reduced pressure to provide a colorless film. The crude material was purified by reverse phase preparatory HPLC (eluent: 10 to 90% acetonitrile, water, 0.1% TFA, gradient elution) to provide the title compound as the first eluting peak.
