Reaction Steps

To a stirred solution of 2-dimethylamino-ethylamine (1.61 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/MeOH) to yield the title compound (1.23 g, 99%) as a light yellow oil. MS (ISP) 269.0 [(M+H)+].
