Reaction Steps

1-(4-(Tetrahydropyran-2-yloxy)phenyl)-4-(N-(4-chlorophenyl)-N-methylamino)piperidine (1.33 g, 3.32 mmol) was suspended in ethanol (80 ml). To this mixture, pyridinium p-toluenesulfonate (0.25 g, 1 mmol) was added and then stirred at 70° C. for 8 hours. Ethanol was removed under reduced pressure, then to this residue, methylene chloride and a saturated aqueous sodium hydrogencarbonate solution were added and stirred. This was extracted with methylene chloride, dried over magnesium sulfate and then filtered. After the resulting filtrate was concentrated under reduced pressure, methylene chloride and n-hexane were added to the residue and the resulting precipitate was filtered to afford 4-(4-(N-(4-chlorophenyl)-N-methylamino)piperidine-1-yl)phenol (922.5 mg, yield 88%) as a light pink powder.
