Procedure
Into a reaction flask was added N-(3-{[(2,5-dichloropyrimidin-4-yl)amino]methyl}phenyl)-3-nitrobenzenesulfonamide (0.20 g, 0.44 mmol), methanol (20 mL), acetic acid (2.0 mL), and water (1 mL). Then iron (0.25 g, 4.5 mmol) powder was added. The reaction mixture was heated at 70° C. for 2 hours. After cooling, the mixture was filtered and washed with EtOAc. The filtrate was concentrated under vacuum to give a residue, which was treated with NaHCO3 (saturated aqueous solution) and EtOAc. The organic layer was dried and concentrated under vacuum. The resulting crude product was then purified by silica gel column chromatography to provide the desired product (46 mg, 25%). LCMS for C17H16Cl2N5O2S (M+H)+: m/z=424.0, 426.0.
