Reaction Steps

2-(4-Iodophenoxy)tetrahydropyran (1.12 g, 3.7 mmol) and 4-[3-(4-trifluoromethylphenyl)propyl]piperidine (1 g, 3.7 mmol) were dissolved in degassed anhydrous toluene (10 ml). Sodium tert-butoxide (0.50 g, 5.2 mmol), tri-tert-butylphosphine tetrafluoroborate (tBu3P.HBF4) (0.09 g, 0.3 mmol) and palladium acetate (0.03 g, 0.15 mmol) were added thereto, and the mixture was heated at reflux under a nitrogen atmosphere for 5 hours. After being allowed to cool to room temperature, water (10 ml) was added to the mixture, followed by extraction with ethyl acetate. The organic layers were combined and washed with water and a saturated sodium chloride aqueous solution, and dried over anhydrous sodium sulfate. After removing insoluble matter by filtration, the solvent was distilled off. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=80:20) to afford the title compound as a pale yellow solid (1.42 g, 86%).
