The invention discloses a method for preparing amide compounds. The method comprises the step of subjecting organic carboxylate with a structure represented by a formula (I) shown in the description and an amine compound with a structure represented by a formula (II) shown in the description to a grinding reaction, thereby preparing an amide compound with a structure represented by a formula (III)shown in the description and an alcohol compound with a structure represented by a formula (IV) shown in the description. According to the synthesis method, a heat source is not required to supply heat, an organic solvent is not required to serve as a medium, the operation is simple, the reaction time is short, the aftertreatment is simple, and thus, industrial production is easy to achieve.
