Reaction Steps
To a solution of 4.94 g tert-Butyl-1-piperazine-carboxylate and 12.66 g 1-Bromo-3-chloropropane in 15 ml DMF (dry) was added 4.08 g K2CO3 and the reaction heated to 50° C. for one minute and stirred at room temperature for additional 3 h. The reaction mixture is pored into 200 ml of water and extracted with DCM. The combined organic phases were washed with water and dried over MgSO4 and evaporated in vacuo. The product was purified by flash column chromatography (n-heptane/ethylacetate 1:1, RF=0.3) Yield 3.9 g.
