The invention discloses a preparation method of an anti-virus drug intermediate. A structure of the intermediate corresponds to a formula V: the formula V is shown in the description. The method comprises the following steps: carrying out reaction in four steps: condensation, reduction, dissociation and splitting on a compound (2S)-N-Boc-4-methoxymethylene pyrrolidine-2-carboxylic acid used as a raw material to finally obtain a (4S)-N-Boc-methoxymethyl-L-proline shown in the formula V. The method disclosed by the invention has cheap and easily-available raw materials, reaction conditions are mild, the selective problem is avoided, the yield is higher, and the method is more suitable for industrial production. The preparation method provided by the invention is high in asymmetric hydrogenation selectivity, simple in splitting conditions, mild in reaction conditions, higher in yield, and suitable for industrial amplified production.
