Reaction Steps
To a stirred solution of 0.200 grams of (3-amino-5-bromo-phenyl)-pyridin-3-yl-methanone (0.72 mmol) in 10 mL of dichloroethane was added 0.87 mL (10.82 mmol) of pyridine followed by the addition of 0.56 mL (7.2 mmol) of methanesulfonyl chloride. The reaction was stirred at 80° C. for 2 hours. The volatiles were removed under reduced pressure affording material which was flash chromatographed (25% EtOAc/hexane to 1:1 EtOAc:hexane to 100% EtOAc) to give 0.150 grams of N-[3-bromo-5-(pyridine-3-carbonyl)-phenyl]-methanesulfonamide.
