Process for Preparing Treprostinil and Intermediate Therefor

摘要

The present invention relates to a synthesis method of high-purity treprostinil, and an intermediate for the same. According to the synthesis method of the present invention, high-purity treprostinil can be synthesized in an economical and efficient manner by using intramolecular Friedel-Crafts allylic alkylation. Accordingly, the synthesis method of the present invention may be effectively used for commercial mass-production of treprostinil.
