The invention discloses a structural formula of a nitrogen mustard derivative N,N-di(2-chloroethyl)-N'-hexadecanoyl-1,4-phenylenediamine, and a preparation method thereof. The preparation method comprises the following steps: preparing N,N-di(2-chloroethyl)-1,4-phenylenediamine; putting the reaction raw materials comprising the N,N-di(2-chloroethyl)-1,4-phenylenediamine, dichloromethane and triethylamine into a reactor, cooling in ice-water bath, stirring, dropwise adding a mixed solution of hexadecanoyl chloride and dichloromethane into the reactor, removing the ice-water bath after addition, conducting reaction at room temperature for 12 to 14 hours, sequentially performing washing, drying and normal-pressure distillation on the reaction liquid after the reaction is conducted completely, and purifying the distilled filter cake to obtain the product. The arylamine nitrogen mustard derivative provided by the invention can effectively reduce the toxic and side effects of nitrogen mustard on the premise of enhancing the treatment index of the nitrogen mustard, and has sterilization and inflammation-diminishing curative effects to reduce the risk of complication caused by the fact that the immunity is reduced after a patient is subjected to chemical therapy.
