Reaction Steps

To a stirred solution of commercially available 5-bromo-thiophene-2-sulfonyl chloride (1.0 g, 3.82 mmol) in THF (8 ml) was added at room temperature triethylamine (0.59 ml, 4.21 mmol), the mixture was cooled (ice-water) and a solution of commercially available N-BOC-ethylenediamine (1.82 ml, 11.5 mmol) in THF (8 ml) was added drop wise. 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) and subsequent crystallization from dichloromethane/hexane to yield the title compound (1.41 g, 96%) as a white solid. MS (ISN) 383.0 [(M−H)−], mp 106° C.
