Versuchsvorschrift

To a solution of 320 mg (0.69 mmol) of 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pentan-3-yl)piperidin-3-yl)acetic acid (Example 71, Step F) and 921 mg (2.42 mmol) of HOBt in DMF (13 mL) was added 0.58 mL (4.15 mmol) of triethylamine. After stirring at room temperature for 40 min, added 270 mg (2.42 mmol) of semicarbazide hydrochloride. The resulting dark red solution was stirred at room temperature for 2.5 h, and then was concentrated under reduced pressure. 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 90% MeCN in water over a 30 min period, where both solvents contain 0.1% TFA) provided the title compound as a light yellow solid.
