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)-(6-methyl-pyridin-3-yl)-methanone 2.4 g (8.77 mmol) and 4-bromo-3-fluoro-benzenesulfonyl chloride 2.16 g (8.77 mmol) stirred in 14 ml pyridine. Purification on silica gel with flash column chromatography gave a light orange solid.
