To a solution of 6-iodopyridin-3-amine (1.077 gm, 4.90 mmole) in dichloromethane (40 ml) and pyridine (1.98 ml, 24.49 mmole) at ice bath temperature was added methanesulfonyl chloride (0.401 ml, 2.444 mmole). The mixture was allowed to warm to room temperature and stir four days. The reaction mixture was treated with 5% acetic acid and allowed to stir 20 min at room temperature. The organic phase was washed with water (2×50 ml), dried (MgSO4) and concentrated in vacuo. The residue was slowly added in portions to rapidly stirred water (100 ml) and the resulting solid collected by filtration, washed with water and dried in vacuo to give the title compound (0.7287 g, 49.9%).
