Reaction Steps

4-[4-(Benzyloxy)benzylidene]piperidine (2.32 g, 8.3 mmol), 1-bromo-4-(tetrahydro-2H-pyran-2-yloxy)benzene (2.35 g, 9.1 mmol), toluene (20 ml), sodium tert-butoxide (1.12 g, 11.6 mmol), palladium acetate (0.075 g, 0.3 mmol) and tri-tert-butylphosphine tetrafluoroborate (0.19 g, 0.7 mmol) were mixed and stirred at 100° C. overnight. Water was poured into the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate, and concentrated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=80:20→50:50) to afford the title compound as a colorless powder.
