Procedure

The N-ethoxycarbonyl-bis(2,2,6,6-tetramethyl-4-piperidyl)-amine is prepared by reacting bis(2,2,6,6-tetramethyl-4-piperidyl)-amine with ethyl chlorocarbonate in chloroform at 10°-20° C. in the presence of aqueous NaOH. The product obtained, which has a purity of 99.2% and melts at 117° C., can be used directly.
