To a solution of 2-bromoethaneamomium bromide (410 mg, 2 mmol) in 20 mL of CH2Cl2 was added triethylamine (3697 μL, 5 mmol). The resulting mixture was stirred at a temperature of about 25° C. for 30 min, then cooled down at 0° C. 2-methylpropane-2-sulfinic chloride (0.73 mL, 2.2 mmol) was added dropwise, kept stirring for 1 hr and allowed to warm up to a temperature of about 25° C. and stirred for about 16 hours. The resulting mixture was condensed and purified by flash chromatography to provide 2-methyl-propane-2-sulfinic acid (2-bromo-ethyl)-amide as a white solid (0.42 g, 86% yield).
