Toluene → 3-Isopropyl-1-(2'-trifluoromethyl-biphenyl-4-ylmethyl)-piperazine

Participants

Reaction Conditions

Reaction Steps

100 mg of 1-(4-bromo-benzyl)-3-isopropyl-piperazine could be combined with 1 equiv. of 2-trifluoromethylphenyl boronic acid, 10 mol % of tetrakis(triphenylphosphine)palladium(0), 2M sodium carbonate solution, toluene and ethanol. The reaction mixture could be heated in a sealed tube at 120° C. overnight. The reaction mixture could be filtered through Celite and concentrated in vacuo. The residue could be diluted with water and extracted with ethyl acetate. The combined organic phases could be washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The crude material could be purified by flash chromatography to afford 3-isopropyl-1-(2′-trifluoromethyl-biphenyl-4-ylmethyl)-piperazine.
