Participants

Reaction Steps

The title compound was prepared according to the general procedures for the synthesis of N-Aryl-benzenesulfonamides previously described using (2-amino-5-chloro-phenyl)-pyridin-3-yl-methanone 5 g (21.5 mmol) and 4-bromo-benzenesulfonyl chloride 5.78 g (21.5 mmol), in 150 ml anhydrous pyridine, overnight at 80° C., followed by flash column chromatography on silica gel to yield a salmon color solid.
