Abstract
The present invention relates to improved processes for the preparation of 1-amino-2,6-dimethylpiperidine whereby the yield is more than 90%. The processes involve the hydrogenation of 1-nitroso-2,6-dimethylpiperidine in the presence of a palladium catalyst partly poisoned with iron ions but in the substantial absence of water or other solubilizing agents added to the reaction vessel.
