|Title:||Derivatives of 4-aminopiperidine and their use as a medicament|
|Abstract:||A subject of the present application is new derivatives of 4-aminopiperidines of formula ##STR00001## in which R.sub.1, R.sub.2 and R.sub.3 represent various radical, and their preparation processes by synthetic methods in parallel in liquid and solid phase. These products having a good affinity with certain sub-types of somatostatin receptors, they are particularly useful for treating the pathological states or diseases in which one (or more) somatostatin receptors are involved.|

6. The compound of claim 1, wherein R.sub.3 is unsubstituted alkyl.
7. The compound of claim 1, wherein R.sub.3 is methyl.
8. The compound of claim 1, wherein Z.sub.12 and Z.sub.22 are optionally substituted phenyl or naphthyl.
