The present invention is directed to novel substituted aminocyclohexanes which are inhibitors of the dipeptidyl peptidase-IV enzyme ('DPP-IV inhibitors') and which are useful in the treatment or prevention of diseases in which the dipeptidyl peptidase-IV enzyme is involved, such as diabetes and particularly Type 2 diabetes. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which the dipeptidyl peptidase-IV enzyme is involved.
Compounds having formula I,
or pharmaceutically acceptable salts, hydrates or N-oxides thereof are provided and are useful for binding to CXCR7, and treating diseases that are dependent, at least in part, on CXCR7 activity. Accordingly, the present invention provides in further aspects, compositions containing one or more of the above-noted compounds in admixture with a pharmaceutically acceptable excipient.

Propylphosphonic anhydride has been shown to be an effective reagent for the synthesis of substituted [1,2,4]triazolo[1,5-a]pyridines from the corresponding N′-hydroxy-N-formimidamides. The reactions worked under mild conditions and exhibited wide functional group tolerance, delivering the triazolopyridines in good to excellent yields and purities.
