Document Type and Number:
WIPO Patent Application WO/2017/076293
Kind Code:
A1
Abstract:
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, a compound J or a compound L without performing isolation, wherein a salt of a compound K is selected from a hydrochloride, sulfate, malate, tartarate, 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.
