Reaction Steps

To a suspension of 10 g (46.66 mmol.) of cis-1-tert-butoxycarbonyl-3,5-dimethyl piperazine and 12.90 g (93.3 mmol.) of potassium carbonate in N,N-dimethylformamide (50 ml) was added, at room temperature, 11.15 g (56 mmol.) of 1-bromo-3-phenylpropane. The mixture was stirred for 40 hours at 120° C., which was then cooled to room temperature. To the reaction system was added water, which was subjected to extraction with ethyl acetate. The organic layer was washed with a saturated aqueous saline solution and dried over magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by means of a column chromatography (ethyl acetate/hexane 20-30%) to give the object compound as a yellow oily product. The yield was 12.21 g (79%).
