Participants

Reaction Steps

To a solution of 42 mg (0.081 mmol) of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-(2-hydroxy-2-methylpropylamino)butan-2-yl)-3-methylpiperidin-2-one (Example 100, Step A) in dioxane (2705 μL) was added carbonyldiimidazole (132 mg, 0.812 mmol). The reaction was heated to 100° for 6 h. Purification of the residue by reversed phase HPLC (Sunfire™ Prep C18 OBD 10 μm column (Waters, Milford, Mass.) (eluent: 60 to 85% MeCN/water (0.1% TFA), gradient elution) provided the title compound.
