Participants

Reaction Steps

Tert-butyl alcohol (2.45 g, 33 mmol) was added to chlorosulfonyl isocyanate solution (4 g, 28.26 mmol) in CH2Cl2 (80 mL) at 0° C. and agitated for 30 min. Triethylamine (19.7 mL) and 3-chloropropylamine HCl (4.29 g, 33 mmol) were added to the mixture and agitated for 2 hr at room temperature, followed by extraction using CH2Cl2 and brine and drying over anhydrous MgSO4. The residue was purified by silica gel column chromatography to give tert-butyl N-(3-chloropropyl)sulfamoylcarbamate (2, 4.17 g, 54%). 1H NMR (300 MHz, CDCl3): δ 5.25 (br, 1H), 3.67-3.62 (m, 2H), 3.28-3.26 (m, 2H), 2.09-2.01 (m, 2H), 1.51 (S, 9H).
