Abstract

The present invention is related to processes for preparing chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines of Formula III, and related synthetic intermediate compounds. The chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines are useful as inhibitors of the Janus Kinase family of protein tyrosine kinases (JAKs) for treatment of inflammatory diseases, myeloproliferative disorders, and other diseases.

Claims

1. A process of preparing a composition comprising an enantiomeric excess of the (R)-enantiomer of a compound of Formula III′
