The present invention relates to a preparation method for a tedizolid compound in Formula I. In Formula I, R is selected from hydrogen, formula A, formula B, benzyl or benzyl substituted by a substituent, the substituent is selected from a group consisting of halogen, nitryl, C1-C6 alkyl, and C1-C6 alkoxy, and R1 is C1-C6 alkyl or C1-C6 alkyl substituted by halogen. The method comprises: generating a compound having a structure as shown in Formula C and a compound having a structure as shown in Formula D by a coupled reaction under the catalysis of a metal catalyst, a substituent of R being defined as above, where X is a leaving group, the leaving group comprising chlorine, bromine, iodine, and sulfonyl oxy such as trifluoromethane sulfonic oxy, methylsulfonyl oxy and benzenesulfonyl oxy, or benzenesulfonyl oxy substituted by one or more substituents, the substituent being selected from a group consisting of halogen, C1-C6 alkyl, and C1-C6 alkoxy.
