Synthesis method of cinnamyl piperazine

The invention discloses a synthesis method of cinnamyl piperazine. The method includes the steps of: a) adding a solvent into a reaction kettle and adding piperazine to uniformly dissolve the piperazine, dropwisely adding hydrochloric acid at 20-25 DEG C until the pH of the reaction solution is 2, which is the terminal, and after the reaction is performed for 1 h, cooling the reaction solution to 20 DEG C, and centrifugally spin-filtering the reaction solution to obtain piperazine dihydrochloride; b) adding the solvent into the reaction kettle, adding the piperazine dihydrochloride and the piperazine with stirring at the same time, and performing a reaction at 68-85 DEG C for 0.5-3 h; c) reducing the temperature to 45-55 DEG C, dropwisely adding cinnamyl chloride, and then increasing the temperature to 60-75 DEG C to perform a temperature maintained reaction for 1-4 h, and reducing the temperature to 10-35 DEG C, performing centrifugal separation, sucking a mother liquid into a distillation reaction kettle, heating the distillation mother liquid to recycle the solvent, adding pure water, and dropwisely adding an alkali liquid to regulate the pH to 9-12, and adding chloroform to perform extraction, drying the mixture, and evaporate-drying the chloroform to obtain the cinnamyl piperazine. The synthesis method reduces production steps and pollutant emission, and is more suitable for modern industrial production.

ARALKYL FORMYL-ALKYL PIPERAZINE DERIVATIVES AND THEIR USES AS CEREBRAL NERVE PROTECTIVE AGENT

The invention relates to aralkyl formyl-alkyl piperazine derivatives, and the use of its comnositions in the manufacture of medicaments for preventing or treating cerebral ischemic apoplexy and nerve protection, acting as central system excitable amino acid (N-methy-D-aspartic acid) antagonists (NMDA). The pharmacological experiments show that they display favorable full or ischemic anti-apoplexy activity, nerve protective activity and low side effects.
