To a solution of 3-amino-5-bromopyridine (0.500 g, 2.89 mmol) in pyridine (2 mL) was added benzenesulfonyl chloride (0.404 mL, 3.18 mmol) dropwise. The reaction mixture was stirred at room temperature (20° C.) for 16 h. After this time, water (5 mL) was added to the reaction mixture. The resulting crystalline solid was collected by filtration, washed with water and dried in the vacuum oven to afford the title compound (0.898 g, 2.89 mmol, quantitative). No further purification was required.
