Reaction Steps

tert-Butyl {2-[(methylsulfonyl)amino]ethyl}carbamate (21 g, 88 mmol) was stirred in a solution of 4 N hydrogen chloride in 1,4-dioxane (97 mL, 388 mmol) for 30 minutes. Trituration with ethyl acetate and hexanes followed by diethyl ether and hexanes gave the desired compound as a gum (19 g, 100%). LCMS calculated for C3H11N2O2S (M+H)+: m/z=139.0.
