Vorschrift

To a solution of 1,4-dioxa-8-azaspiro[4,5]decane (5.0 g, 35 mmol) in THF (25 mL) was added triethylamine (5 mL, 36 mmol) followed by N,N-dimethylsulfamoyl chloride (3.7 mL, 35 mmol). The resulting white mixture was stirred at room temperature for 1 h. The solids were removed by filtration and the solution was concentrated to give the title compound as a white solid (8.7 g, 100% yield). 1H NMR (300 MHz, CDCl3) δ: 3.93 (4H, s), 3.35 (4H, t, J=5.8 Hz), 2.78 (6H, s), 1.73 (4H, t, J=5.8 Hz). LCMS (M+H) calcd for C9H19N2O4S: 251.10; found: 251.24.
