Method for synthesizing p-methoxybenzyl [3-(aminomethyl)-oxetane-3-yl]carbamate p-chlorobenzoate

The invention provides a method for synthesizing p-methoxybenzyl [3-(aminomethyl)-oxetane-3-yl]carbamate p-chlorobenzoate. The method comprises the following steps: a, preparing a compound 2 from a cyclic imido group substituted compound 1, wherein the cyclic imido group is any one of phthalimide, succimide and maleimide; b, carrying out an amination reaction on a primary amine and the compound 2to generate a compound 3; and c, reacting the compound 3 with 4-chlorobenzoic acid to obtain a compound 4. A reaction route is shown in the description. The synthesis method is friendly to the environment, and is suitable for large-scale industrial production. 本发明提供种[3-(胺甲基)-氧杂环丁烷-3-基]氨基甲酸对甲氧基苄酯对氯苯甲酸盐的合成方法，其特征在于，包括如下步骤：a.使用环状酰亚胺基团取代化合物1的溴基生成化合物2，环状酰亚胺基团为邻苯二甲酰亚胺、丁二酰亚胺、马来酰亚胺的任种；b.使用伯胺与化合物2进行胺化反应生成化合物3；c.化合物3与对氯苯甲酸反应得到化合物4；反应路线如下：本发明提供的合成方法更加环保，并且适于大规模工业化生产。
