55 mg of 3-phenyl-1-(2′-trifluoromethyl-biphenyl-4-ylmethyl)-piperazine was dissolved in THF, 2 equiv. of acetylchloride and 2 equiv. of N,N-diisoproylethylamine were added. The reaction was shaken at room temperature overnight. The solvent was removed in vacuo, the residue was dissolved in DCM, washed with 1M aqueous sodium hydroxide solution, then dried over sodium sulfate, filtered and concentrated in vacuo. The crude residue was purified by column chromatography to afford the title compound as free base. Addition of 1 equiv. of 1M HCl in dioxane and concentration in vacuo afforded 27 mg of the title compound as hydrochloride salt. Yield 40% ES MS m/z 439
