1,3-bis(methoxymethyl)urea

反応条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 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). the deposit was filtered off under suction The filter residue was stirred with 300 parts of petroleum ether 48 parts of colourless crystals melting at 62° to 65° C. were left after drying
