A novel process for the preparation of proline derivatives of formula (I) wherein,R1 is selected from C1-7-alkyl or from formula (II) wherein R4 is selected from C1-7-alkyl, halogen-C1-7-alkyl or from phenyl which is optionally substituted by halogen; R2 is selected from halogen or halogen-C1-7-alkyl; and R3 is selected from hydrogen, halogen, halogen-C1-7-alkyl, C1-7-alkoxy, halogen-C1-7-alkoxy or from a 5- or 6-membered heterocyclic ring containing one or two nitrogen atoms, the ring which is optionally substituted by C1-7-alkyl or halogen is described. 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.
一种用于制备式(I)的脯氨酸衍生物的新型方法,其中,R1从C1-7-烷基或从式(II)中选择,其中R4从C1-7-烷基、卤代C1-7-烷基或从苯且可以被卤素取代中选择;R2从卤素或卤代C1-7-烷基中选择;R3从氢、卤素、卤代C1-7-烷基、C1-7-烷氧基、卤代C1-7-烷氧基或从含有一个或两个氮原子的5-或6-成员杂环环中选择,该环可以被C1-7-烷基或卤素取代。式(I)的脯氨酸衍生物是优选的半胱氨酸蛋白酶S的抑制剂,因此可用于治疗代谢性疾病,如糖尿病、动脉粥样硬化、腹主动脉瘤、外周动脉疾病和糖尿病肾病。
