反応手順
34 parts of 1,2,2,6,6-pentamethyl-4-aminopiperidine were dissolved in 100 parts of toluene, followed by the dropwise addition of 25° C. of 18.8 parts of 93% methoxymethyl isocyanate. After stirring for 1 hour at 25° C., the toluene was evaporated in vacuo and the residue was crystallised from cleaning spirit, giving 42.5 g of colourless crystals melting at 105° C.
