Reaction Steps

To a solution of 2-aminoethanol (0.24 mL, 4.0 mmol), and triethylamine (1.5 mL, 11 mmol) in anhydrous THF (15 mL) was added 4-bromo-2-fluorobenzene-1-sulfonyl chloride (1.0 g, 3.7 mmol) portion wise and the reaction mixture stirred at room temperature for 16 h. The reaction was filtered, the filtrate was concentrated and the residue was purified by column chromatography (silica, ethyl acetate/hexanes gradient) to afford the desired product (850 mg, 77%): ESI MS m/z 298 [C8H9BrFNO3S+H]+.
