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.
