Procedure

To a stirred solution of 2-amino-1,3-propanediol (1.26 g, 13.8 mmol) in THF (20 mL) was added at 0° C. (ice water bath) commercially available 5-chloro-thiophene-2-sulfonyl chloride (1.0 g, 4.61 mmol) and triethylamine (0.71 mL, 5.07 mmol). The reaction mixture was stirred at room temperature for 16 h and evaporated. The crude product was further purified by flash chromatography (ethyl acetate/heptane) to yield the title compound (0.96 g, 77%) as an off-white solid. MS (ISP) 272.2 [(M+H)+], mp 101° C.
