摘 要:基于溴苄与2-氨基苯甲醇的N-烷基化反应制备2-(苄基氨基)苯基甲醇的条件进行了优化探究。利用单因素法,探讨了反应溶剂、碱的种类及用量、反应温度、时间、物料比等对反应的影响,并通过正交实验法获得影响反应因素的顺序为:原料比>反应温度>反应时间>碱的用量,从而优化了反应条件。在优化条件下,合成了一系列N-(芳甲基)-2-(2-羟甲基苯基氨基)乙酰胺类化合物,收率为58%~69%。

Abstract:The reaction conditions for N-alkylation of 2-aminobenzyl alcohol with benzyl bromide were optimized and 2-(benzylamino) benzyl alcohol was obtained. The effects of the types and loading of solvent and base, reaction temperature, reaction time and material ratio on the reaction were systematically studied using the single-factor method. Furthermore, by orthogonal experiment, it was found that the order of the factors affecting the reaction was raw material ratio>reaction temperature>reaction time>the amount of base. And then an optimum process conditions were thus determined. Moreover, under this optimum process conditions, a series of N-arylmethyl-2-((2-hydroxymethylphenyl)amino)acetamides were prepared at a yield between 58%~69%.
