Participants

Reaction Steps

To a solution of N′-ethyl-N,N-dimethylethane-1,2-diamine (0.62 mL, 4.4 mmol) in methylene chloride (10 mL) was added 6-chloropyridine-3-sulfonylchloride (0.85 g, 4 mmol; described in: Naegeli, C. et al. Helv. Chim. Actal. 1938, 21, 1746-1750) dissolved in methylene chloride (10 mL) dropwise. The reaction mixture was stirred for 30 min at room temperature followed by the extraction with aqueous HCl (5%). The acidic water layer was alkalized with an aqueous saturated solution of NaHCO3 and extracted with methylene chloride. The organic phase was dried (Na2SO4) and evaporated in vacuo to give 0.7 gram (60% yield) of the title compound: MS (ES) m/z 292 (M++1).
