Tert-butyl {[methyl(tetrahydrofuran-3-yl)amino]sulfonyl}carbamate → N-methyl-N-(tetrahydrofuran-3-yl)sulfamide

Participants

Reaction Steps

tert-butyl {[methyl(tetrahydrofuran-3-yl)amino]sulfonyl}carbamate (1.47 g, 5.23 mmol) was dissolved in 70 mL of CH2Cl2 and 45 mL of trifluoroacetic acid. After 1 h the solution was concentrated in vacuo, diluted in CH2Cl2, washed with saturated aqueous NaHCO3 and brine, then dried over Na2SO4. The solution was concentrated in vacuo to afford the title compound. 1H NMR (600 MHz, DMSO-d6) δ 4.25-4.31 (m, 1H); 3.79-3.84 (m, 1H); 3.58-3.66 (m, 2H); 3.47-3.52 (m, 1H); 2.56 (s, 3H), 2.04-2.10 (m, 1H); 1.81-1.88 (m, 1H).
