Reaction Steps
To a stirred solution of diethanolamine (1.45 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 (1.15 g, 88%) as a white solid. MS (ISN) 284.3 [(M−H)−], mp 69° C.
