实验步骤: 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. The reaction mixture would then be filtered through Celite concentrated in vacuo The residue would then be purified by flash chromatography

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: This compound could be made in the following manner: 2 g of 4-Bromobenzyl bromide and 1 equ. piperazine in acetonitrile would be stirred at room temperature and 1.1 g of potassium carbonate would be added. The reaction would be stirred at room temperature overnight. The solution would then be filtered through Celite and concentrated in vacuo to afford the crude product. Purification would be done by flash chromatography using a methylene chloride/methanol gradient. The reaction The solution would then be filtered through Celite concentrated in vacuo
