Participants

Conditions

Temperature: 120 °C

Procedure

100 mg of 1-(4-Bromo-benzyl)-3-phenyl-piperidine was combined with 862 mg of 2-(Trifluoromethyl)phenyl boronic acid, 35 mg of tetrakis(triphenylphosphine)palladium(0), 1.015 mL of 2M sodium carbonate solution, 2.7 mL toluene and 1.4 mL ethanol. The reaction mixture was heated in a sealed tube at 120° C. overnight in an oil bath. The reaction mixture was filtered through Celite and concentrated in vacuo. The residue was purified by reverse phase HPLC. ES MS (+) m/z 396, 100% yield
