Versuchsvorschrift
36.3 parts of β-(2,2,6,6-tetramethylpiperidin-4-yl)-aminopropionic acid hydrazide were dissolved in 100 parts of toluene, followed by the dropwise addition of 28.2 parts of 93% methoxymethyl isocyanate. After stirring for 1 hour at 25° C., the deposit was filtered off under suction. The filter residue was stirred with 300 parts of petroleum ether and refiltered under suction. 48 parts of colourless crystals melting at 62° to 65° C. were left after drying. C18H36N6O5 (416.5).
