Process for the preparation of racemic 2-{(2-(4-hydroxyphenyl)ethyl)thio}-3-(4-(2-{4-((methylsulfonyl)oxy)phenoxy}ethyl)phenyl)-propanoic acid

摘要

The present invention provides a process for the preparation of substantially racemic 2-{[2-(4-hydroxyphenyl)ethyl]thio}-3-[4-(2-{4-[(methylsulfonyl)oxy]phenoxy}ethyl)phenyl]-propanoic acid which comprises reacting 2-{[2-(4-hydroxyphenyl)ethyl]thio}-3-[4-(2-{4-[(methylsulfonyl)oxy]phenoxy}ethyl)phenyl]propanoic acid enriched in one enantiomer with a base in an inert solvent.
