反応手順
36.3 parts of β-(2,2,6,6-tetramethylpiperidine-4-yl)amino-propionic acid hydrazide are 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 is filtered off under suction. The filter residue is stirred with 300 parts of petroleum ether and refiltered under suction. 48 parts of colourless crystals melting at 62° to 65° C. are left after drying.
