The invention discloses a method for preparing a dexmedetomidine hydrochloride key intermediate. The method comprises the following steps: by taking 1-(1-chloroethyl)-2,3-dimethyl benzene and N-Boc-imidazole as raw materials, carrying out a low-temperature reaction in an aprotic organic solvent in the presence of Lewis acid, thereby obtaining a compound of a formula (III). According to the method disclosed by the invention, the starting materials refer to industrialized popular commodities and are stable in properties and easy to preserve, the defect that the raw materials are unstable in the process of preparing the conventional dexmedetomidine hydrochloride intermediate is overcome, and the method is high in reaction yield, suitable for industrial production and has high application value. The structural formula is as shown in the specification.
