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 2 g (8.7 mmol) and 4-bromo-3-fluoro-benzenesulfonyl chloride 2.35 g (8.77 mmol) in 15 ml pyridine. Purification with silica chromatography eluted with dichlorometane:10-ethyl acetate gave a yellow powder.
