The invention discloses a copper-catalyzed C-N coupling method adopting N,N-disubstituted hydrazide as a ligand. The method comprises the steps of adopting aromatic halide and an amine compound as raw materials, adopting an alcohol compound as a solvent, adopting copper or a copper compound as a catalyst, adopting the N,N-disubstituted hydrazide with a structural formula as shown in a formula I or a formula II as the ligand, and under the existence of alkali, carrying out C-N coupling reaction at the temperature of 10 to 130 DEG C so as to generate an N-aryl compound. The copper-catalyzed C-N coupling method provided by the invention is mild in reaction conditions, high in chemoselectivity, wide in substrate application range, and simple to operate; a product is simple, easy to separate, green and environment-friendly; and the product yield is higher. According to the figure, R1 and R2 are selected from methyl, phenyl, 4-methoxyphenyl, 4-nitrobenzophenone, 2-methylphenyl, 2-isopropyl phenyl; R3 is hydrogen or methoxyl.
