Continuous process for the preparation of 4-aminopiperidines |
| abstract |
The invention relates to a process for the preparation of N-monosubstitutedn4-aminopiperidines through continuous, single-stagenReaction of a 4-oxopiperidine with a primary amine and hydrogennunder hydrogenation conditions with or without solvent. ThenStarting materials can be passed over a fixed support catalystnbe the one or more metals of VIII.nSubgroup of the periodic table contains. The reaction is generalncarried out at 80 to 200 ° C. The products are raw materialsnfor the production of sterically hindered amines. |
