摘　　要：发展了一条高效、简单的药物中间体β-卤代苯乙胺的合成方法.二苄胺和溴乙酸乙酯作为起始原料,经历取代、加成、催化氢化、氯代和酰化5步反应,以中等产率制备得到目标产物2-乙酰氨基-3-氯-3-(4-甲氧基苯基)丙酸乙酯,对合成过程中的中间产物及目标产物的制备进行了条件优化,确定了最佳反应路线,同时还通过熔点、核磁共振氢谱和碳谱对目标产物进行了表征.此合成方法为含多官能化苯乙胺结构的药物分子的合成提供了一种便利途径.A highly efficient and simple method for the synthesis of pharmaceutical intermediates ofβ-halogenated phenethylamine has been developed.Using ethyl bromoacetate and dibenzylamine as starting material,the desired ethyl 2-acetamido-3-chloro-3-（4-methoxyphenyl）propanoate was synthesized through sequential substitution,addition,catalytic hydrogenation,chlorination and acylation.The strategy provides a convenient way for natural products and pharmaceutical molecules containing multifunctional structural units of ethylamine.The reaction conditions were optimized and the optimum synthetic route was determined.Moreover,the target product was characterized by melting point,^1H NMR and ^13C NMR.
