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 (100 ml) was added, at room temperature, 11.97 g (70 mmol.) of benzyl bromide. The mixture was stirred for 16 hours at 120° C. 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, which was dried over magnesium sulfate, followed by distilling off the solvent. The residue was purified by means of a column chromatography (ethyl acetate/hexane 30%) to give the object compound as a pale yellow oily product. The yield was 13.56 g (95%).
