These drugs compared with traditional organic drugs with high pharmacological activity. In organic synthesis, as the active pharmaceutical intermediates, further synthesis of many types of organic compounds. Research has a strong meaning. N-tert-butoxycarbonyl piperazine piperazine synthesized by starting with the acetic acid salt reaction occurs, anhydrous ethanol as solvent, then add the second di-tert-butyl carbonate obtained by acylation of N-tert-butoxycarbonyl piperazine crude. In the reaction process, the need for strict control of pH value and temperature, in order to reduce the by-product formation. After treatment with ethyl acetate as extracting agent to remove unreacted raw materials, isomers and by-products and other impurities. Finally, access to qualified N-Boc piperazine-based products. The experimental process analysis, experimental data. Obtained N-tert-butoxycarbonyl piperazine some of the physical and chemical properties, can be seen that this process is feasible, stable product quality, better than the other process routes. Has a broad market efficiency and economic profit. Key words: N-tert-butoxycarbonyl piperazine; piperazine; two-di-tert butyl carbonate; pharmaceutical intermediates; II 目录 目 录
