Ethylenedamine derivatives having a halogenated carbamate group and an acyl group can be produced by performing the catalytic hydrogenation of an aminonitrile having a halogen-substituted carbamate group in the presence of- an acid and then performing the acylation of the resulting product. The aminonitrile (i.e., a starting material) can be prepared in a high yield by performing the halogenated carbamatation of an amino acid amide in the presence of water and then reacting the resulting product with a deoxidizing agent such as a vilsmeier reagent.
具有卤代氨基甲酸酯基团和酰基的乙二胺衍生物可通过在酸存在下对具有卤代氨基甲酸酯基团的氨基腈进行催化氢化反应,然后对所得产物进行酰化反应制得。氨基腈(即起始原料)可以通过在有水的情况下对氨基酸酰胺进行卤代氨基甲酸化反应,然后使所得产物与脱氧剂(如维尔斯梅尔试剂)反应,从而以较高的产率制备。
