Acetic Acid → (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-1-((S)-1-morpholinobutan-2-yl)piperidin-2-one

To a solution of 100 mg (0.225 mmol) of (S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)butanal (Example 91, Step C) in DCE (2420 μL) was added morpholine (200 μL, 2.297 mmol), acetic acid (1.288 μL, 0.023 mmol) and sodium triacetoxyborohydride (95 mg, 0.450 mmol). The reaction mixture was stirred at room temperature for 18 hours. The reaction was quenched with sat. sodium bicarbonate solution and extracted with DCM (2×10 mL). The combined organic layers were washed with sat NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure to afford the crude title compound as an oil.
