Reaction Steps

4-(N-(4-chlorophenyl)-N-methylamino)-piperidine (2.52 g, 11.22 mmol), 2-(4-bromophenoxy) tetrahydropyran (2.89 g, 11.22 mmol), palladium acetate (50 mg, 0.22 mmol), (S)-(−)-2,2-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) (212 mg, 0.34 mmol) and tert-butoxy sodium (1.51 g, 15.71 mmol) were refluxed with heating in toluene (30 ml) under nitrogen atmosphere for 3 hours. Ethyl acetate and water were added into the reaction solution and stirred, then the resulting precipitate was removed by filtration through Celite, thereafter the filtrate was extracted with ethyl acetate. The organic phase was washed with saturated brine, dried over magnesium sulfate, and then filtered. After the resulting filtrate was concentrated under reduced pressure, the residue was purified by silica gel column chromatography (n-hexane/ethyl acetate=20/1) to afford 1-(4-(tetrahydropyran-2-yloxy)phenyl)-4-(N-(4-chlorophenyl)-N-methylamino)piperidine (1.33 g, yield 30%) as a light yellow powder.
