YieldReaction ConditionsOperation in experiment
40% A solution of 510 mg (2.96 mmol) of <strong>[187143-22-2]6-methanesulfonylpyridin-3-ylamine</strong> in 1.25 mL of AcOH was added a solution of 0.15 mL (2.96 mmol) of bromine in 0.5 mL of AcOH at room temperature dropwise. The resulting slurry was stirred for 1 hour. The reaction was carefully basified to pH = 10 with 6 M NaOH. The solution was then extracted with two 150 mL portions of dichloromethane, dried with magnesium sulfate, filtered, and concentrated in vacuo. The crude mixture showed a 3:1 mixture of product:dibromo product by NMR. These two products were separated by silica chromatography (hexanes/EtOAc) to afford 294 mg (40%) of 2-bromo-<strong>[187143-22-2]6-methanesulfonylpyridin-3-ylamine</strong>.
