PREPARATION METHOD FOR TEDIZOLID, TEDIZOLID INTERMEDIATE, AND PREPARATION METHOD THEREFOR

摘要

The invention relates to a method for preparing an oxazolidinone intermediate. Specifically, a synthesis procedure for the intermediate comprises: directly performing a "one-pot" reaction on a compound I, compound J or compound L without performing isolation, wherein a salt of a compound K is selected from a hydrochloride, sulfate, malate, tartrate, p-toluenesulfonate, or lactate, and wherein the symbol * in a compound indicates an atom of an R-type chirality or an S-type chirality or a racemate thereof.
