The invention provides a preparation method of 2-[(2-benzothiazolylmethyl)thio]-6-ethoxybenzothiazole. The method includes reacting a compound (II) and a compound (III) in a solvent under an alkalinecondition with or without a catalyst to obtain a compound (I) that is the 2-[(2-benzothiazolylmethyl)thio]-6-ethoxybenzothiazole. The invention further provides a preparation method of the compound (II), including reacting a compound (IV) with a nitrosation agent and a copper agent in order in a solvent. The invention further provides a preparation method of the compound (III), including reactinga compound (V) with a sulfurizing agent in a solvent to obtain the compound (III). According to the methods, raw materials are cheap and easily available or easy to prepare, reaction conditions are mild, and selectivity and yields are high. The intermediates and a product are purified through crystallization instead of column chromatography and the methods are suitable for industrialization.
