실험 절차

27.7 g (0.1 mol) of tetradecyl chlorocarbonate are added slowly to a solution of 19.4 g (0.1 mol) of 2,2,6,6-tetramethyl-4-piperidinol hydrochloride in 150 ml of dichloromethane, maintaining the temperature at between 0° C. and 5° C. After the end of the addition, the mixture is stirred for 2 hours at ambient temperature, and a solution of 8.8 g (0.22 mol) of NaOH in 50 ml of water is then added slowly, with cooling to -10° C.
