The present invention is concerned with a process for the preparation of the compound {3-[2(R)-[(1R)-1-[3,5-bis(trifluoromethyl)phenyl]ethoxy]-3(S)-(4-fluorophenyl) -morpholin-4-yl]methyl]-5-oxo-4,5-dihydro-[1,2,4]-triazol-1-yl}phosphonic acid, and pharmaceutically acceptable salts thereof. This compound is useful as a substance P (neurokinin-1) receptor antagonist. In particular, the compound is useful e.g., in the treatment of emesis and inflammatory diseases.

Process for {3-[2(R)-[(1R)-1-[3,5-bis(trifluoromethyl)phenyl]ethoxy]-3(S)-(4-fluorophenyl)morpholin-4-yl]methyl]-5-oxo-4,5-dihydro-[1,2,4]-triazol-1-yl}phosphonic acid

A novel process is provided for the preparation of chiral trans-2,3-disubstituted 5-oxotetrahydropyrans of structural formula (I): wherein Ar is optionally substituted phenyl and P is a primary amine protecting group. These compounds are useful in the synthesis of dipeptidyl peptidase-IV inhibitors for the treatment of Type 2 diabetes. Also provided are useful intermediates obtained from the process.
