Procedure

This compound could be made in the following manner: 1-(4-Bromo-benzyl)-piperazine would be combined with 1 equ of 2-(Trifluoromethyl)phenyl boronic acid, 10 mol % of tetrakis(triphenylphosphine)palladium(0), 2M sodium carbonate solution, toluene and ethanol. The reaction mixture would be heated in a sealed tube at 120° C. overnight in an oil bath. The reaction mixture would then be filtered through Celite and concentrated in vacuo. The residue would then be purified by flash chromatography.
