実験手順

259 mg (0.50 mmol) of 2-(2-((3R,5R,6S)-5-(3-Chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pentan-3-yl)piperidin-3-yl)acetyl)hydrazinecarboxamide (Example 76, Step A) was suspended in 2 N aqueous sodium hydroxide (16 mL) and heated at reflux for 3.25 h. Upon cooling to room temperature, the mixture was acidified with conc. HCl until strongly acidic and then extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated. Purification of the residue by reversed phase prep. HPLC (Sunfire™ Prep C18 OBD 10 μm column (Waters, Milford, Mass.), gradient elution of 40% MeCN in water to 75% MeCN in water over a 30 min period, where both solvents contain 0.1% TFA) provided the title compound as a white solid.
