Procedure

156 parts of 4-amino-2,2,6,6-tetramethylpiperidine were heated to 150° C. and ethylene oxide was introduced until 44 parts thereof had been taken up. After fractional distillation, there were obtained 111 parts of 4-(β-hydroxy-ethyl)amino-2,2,6,6-tetramethylpiperidine boiling at 125° C./0.1 torr (melting point 89° to 91° C.) as well as compound 4) as higher boiling fraction.
