The invention provides a preparation method of 2-(4-benzyloxyphenyl)ethanol. The preparation method comprises the following steps: 1) subjecting phenol to reacting with chloroacetyl chloride under the catalysis of aluminum trichloride to obtain a compound as shown in a formula II; 2) subjecting the compound as shown in the formula II to reacting with benzyl halide under an alkaline condition to obtain a compound as shown in a formula III, wherein the benzyl halide is one selected from benzyl bromide and benzyl chloride; 3) performing reduction treatment on the compound as shown in the formula III, and adjusting a reaction system to be an alkaline system to obtain a compound as shown in a formula IV; and 4) under the action of a catalyst, reducing the compound as shown in the formula IV under a hydrogen condition to obtain the 2-(4-benzyloxyphenyl)ethanol as shown in the formula I. The preparation method has the advantages of low cost, mild reaction conditions, safety in operation and less three-waste pollution, and is beneficial to being applied to industrial production.
