摘 要:基于溴芐與2-氨基苯甲醇的N-烷基化反應制備2-(芐基氨基)苯基甲醇的條件進(jìn)行了優(yōu)化探究。利用單因素法,探討了反應溶劑、堿的種類(lèi)及用量、反應溫度、時(shí)間、物料比等對反應的影響,并通過(guò)正交實(shí)驗法獲得影響反應因素的順序為:原料比>反應溫度>反應時(shí)間>堿的用量,從而優(yōu)化了反應條件。在優(yōu)化條件下,合成了一系列N-(芳甲基)-2-(2-羥甲基苯基氨基)乙酰胺類(lèi)化合物,收率為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%. |
Key words:2-aminobenzyl alcohol; N-alkylation; synthesis; orthogonal experiment |
