Vorschrift

To a solution of (4S)-4-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-3-methyl-2-oxopiperidin-1-yl)-2,2-dimethylhexanenitrile prepared above in Step G (77 mg, 0.135 mmol) in THF (2.69 mL) was added 3 N hydrochloric acid in water (1.35 μL, 4.04 mmol) at rt. After being stirred at rt for 4 h, the reaction was diluted (sat. aq. NaCl) and extracted (2×EtOAc). The combined organic layers were washed (sat. aq. NaCl solution), dried (Na2SO4), and concentrated under reduced pressure to provide the title compound as a colorless foam.
