The invention discloses a preparation method of
tedizolid phosphate and an intermediate thereof. The preparation method of a
tedizolid phosphate intermediate II comprises the following steps: 1, in anorganic
solvent, under a condition of presence of a catalyst and
zinc powder, performing a reaction on 3-
fluorine-4-bromophenyl amino benzyl
formate so as to obtain a solution of a
tedizolid phosphate intermediate III; and 2, in an
organic solvent, under a condition of presence of a
palladium catalyst and a base, performing a
coupling reaction on the solution of the tedizolid phosphate intermediate III obtained in the step 1 with 2-methyl-5-(5-bromopyridine-2-yl)
tetrazole, so as to obtain the tedizolid phosphate intermediate II. The preparation method disclosed by the invention is free of toxic
reagent, mild in reaction condition, safe to operate,
environmentally friendly, high in yield, high in prepared product purity and low in production cost.
Tedizolid phosphate prepared from the tedizolid phosphate intermediate II disclosed by the invention is high in yield, high in purity, capable of meeting
raw material medicine standards and applicable to industrial production.
