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.

The invention provides a process for preparing 11 β-hydroxy steroid dehydrogenase type 1 inhibitors of formula 2 via a catalyzed reaction between a compound of formula 1 and a compound of formula R
2
LG in the presence of base:
where R
1
, R
2
, X, Y, and LG are described in the specification. Exemplary catalysts contain palladium and one or more phosphine ligands. The process can be performed in a stereoselective manner to give enantiomerically enriched products.

The present invention is related to processes for preparing chiral substituted pyrazolyl pyrrolo[2,3-di]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.
