, (2020/03/23)
The invention relates to a preparation method of a gaucher disease treatment drug eliglustat. The preparation method comprises the following steps: using S-isopropyl-2-oxazolidinone as a raw material,carrying out a condensation reaction, a bromination reaction, a substitution reaction, a hydrolysis reaction, a condensation reaction and a reduction reaction to obtain eliglustat, and carrying out salt forming and two-step purification on the eliglustat to obtain high-purity eliglustat tartrate. According to the method, the chiral center is completely synthesized from the starting material, so that the reaction steps are reduced, the production period is shortened, the synthesis efficiency of the chiral center is improved, the yield of the final product is improved, the salt forming steps are optimized in detail, and the qualified quality control of the bulk drug is ensured.
