The invention provides a preparation method of an oxazolidinone compound, particularly relates to a novel preparation method of (S)-[N-3-(3-fluorine-4-(4-phenyl piperazinyl) phenyl)-2-oxo-5-oxazolidinyl] methylacetamide, and relates to the medical field. According to the existing preparation method, the reagent selection effect is non ideal, so that the existing preparation method is high in post-treatment operation difficulty, low in yield and unfavorable for industrial expansion. All the steps are improved; use of raw materials with relatively high toxicity is avoided, and better reagents and a treatment process which is easier to operate are selected; the product yield is greatly increased; the process is more stable and favorable for industrial production.
