Reaction Steps

Cis(±)2-[4-(dibenzylamino)-3-methoxypiperidin-1-yl]ethanol (Intermediate 170, 740 mg, 2.1 mmol) was reacted with methanesulfonyl chloride (0.20 mL, 2.5 mmol) in the presence of triethylamine (0.41 mL, 2.9 mmol) as described for Intermediate 6. The crude product was presumed to be unstable and was used without further purification directly for the next step.
