Reaction Steps

To a solution of 5-bromopyridin-3-amine (1.00 g, 5.78 mmol) in pyridine (3.00 mL) was added benzenesulfonyl chloride (0.75 mL, 5.78 mmol) dropwise at 0° C. The mixture was stirred for 40 min at room temperature. The resulting solid was filtered, washed with water, and dried under vacuum to give N-(5-bromopyridin-3-yl)benzenesulfonamide (1.39 g, 77%) as a brown solid. 1H-NMR (DMSO-d6, Varian 400 MHz) δ 7.58-7.68 (4H, m), 7.79-7.81 (2H, m), 8.27 (1H, d, J=2.4 Hz), 8.37 (1H, d, J=2.0 Hz), 10.91 (1H, brs).
