ABSTRACT:
Preparation of 4-acylamino-2,2,6,6-tetramethylpiperidines from 4-amino-2,2,6,6-tetramethylpiperidine and acid anhydrides carried out in the presence of carboxylic acids, whereupon the carboxylic acid is eliminated, using water at elevated temperature, from the initially formed carboxylate salt of the 4-acylamino-2,2,6,6-tetramethylpiperidine. In this process, no salt-like by-products arise.
