摘 要:目的:制备盐酸美克洛嗪。方法:以无水哌嗪(Ⅱ)与间甲基苄氯(Ⅰ)反应,反应结束后加入浓盐酸析晶,直接得到间甲基苄基哌嗪盐酸盐(Ⅲ);Ⅲ再和[4-氯苯基]苯甲基氯(Ⅳ)作用得到美克洛嗪(Ⅴ),盐酸化即得目标化合物盐酸美克洛嗪(Ⅵ)。结果及结论:产物经熔点(mp)、红外光谱(IR)、核磁共振氢谱(1HNMR)、核磁共振碳谱(13CNMR)、质谱(MS)和元素分析确证。该法操作简便,收率较高(81.8%),产物纯度98.5%,适于工业化生产。Objective: To design and synthesize meclizine hydrochloride. Methods: Using 1-(chloromethyl)-3-methylbenzene ( Ⅰ ) and piperazine ( Ⅱ ) as the starting materials, 1-[ (3-methylphenyl)methyl] piperazine dihydrochloride ( Ⅲ ) was synthesized. Then Ⅲ reacted with (4-chlorophenyl) phenymethyl chloride (Ⅳ) to produce meclizine ( Ⅴ ), and finally obtained the title compound meclizine hydrochloride ( Ⅵ ) by acidifying with hydrochloric acid. Results and Conclusions: The structure of the target compound was identified by mp, IR, ^1HNMR, ^13CNMR, MS and element analysis. This new synthetic scheme can be industrialisated because of the advantages of a lower cost, higher yield (81.8%) , simpler operation, and milder reaction conditions.
