Dichloromethane → 2-nitro-N-(2-pyridin-3-ylethyl)benzenesulfonamide

Participants

Reaction Steps

2-Nitrobenzene sulfonyl chloride(11.64 g) was added to a dichloromethane solution (100 ml) of 3-(2-aminoethyl)pyridine(6.11 g) and triethylamine(9 ml) at 0° C. The mixture was stirred at room temperature for 2 hours. Water was added to the reaction mixture, followed by extraction with dichloromethane. The organic layer was dried with anhydrous sodium sulfate, and condensed under reduced pressure. The residue was crystallized from ethyl acetate to give the title compound(5.06 g) as a yellow powder.
