The invention relates to a method for preparing 2-amino-N-(2,2,2-trifluoroethyl)acetamide and its salt. The method for preparing 2-amino-N-(2,2,2-trifluoroethyl)acetamide and its salt comprises the following steps: reacting N-phthaloyl-protected glycine with trifluoroethylamine or its salts to form amide, removing the above protective group under the action of hydrazine hydrate to obtain crude2-amino-N-(2,2,2-trifluoroethyl)acetamide, carrying out a salt formation reaction on the crude 2-amino-N-(2,2,2-trifluoroethyl)acetamide and an acid to obtain the salt of the 2-amino-N-(2,2,2-trifluoroethyl)acetamide, and adding an alkali to dissociate the 2-amino-N-(2,2,2-trifluoroethyl)acetamide. The method has the advantages of low price of a deprotection reaction reagent used in the invention, simplicity in operation, no use of flammable and explosive hydrogen, realization of the reaction temperature from room temperature to the reflux temperature of a solvent, and mild reaction conditions, and is very suitable for the production of industrial devices.
