Reaction Steps

This compound was made in the following manner: 50 mg of 3-(S)-benzyl-1-(2′-chloro-5′-methyl-biphenyl-4-ylmethyl)-piperazine was dissolved in THF, 2 equ. of bromoethane and 2 equ. of N,N-diisopropylethylamine were added. The reaction was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure. The residue was diluted with DCM, washed with saturated aqueous sodium bicarbonate 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 the free base. Treatment with 1 equ. 1M HCl in dioxane and concentration in vacuo afforded 29.5 mg of the corresponding hydrochloride salt. Yield 51%, ES MS m/z 419/421.
