The present invention relates in part to a process for the preparation of a proline derivative of formula I
wherein,
R
1
is C
1-7
-alkyl or
wherein R
4
is selected from the group consisting of C
1-7
-alkyl, halogen-C
1-7
-alkyl and phenyl optionally substituted by halogen;
R
2
is halogen or halogen-C
1-7
-alkyl; and
R
3
is selected from the group consisting of hydrogen, halogen, halogen-C
1-7
-alkyl, C
1-7
-alkoxy, halogen-C
1-7
-alkoxy and a 5- or 6-membered heterocyclic ring containing one or two nitrogen atoms, said ring being optionally substituted by C
1-7
-alkyl or halogen.
The proline derivatives of the formula I are preferential inhibitors of the cysteine protease Cathepsin S and are therefore useful to treat metabolic diseases like diabetes, atherosclerosis, abdominal aortic aneurysm, peripheral arterial disease and diabetic nephropathy.
