Reaction Steps

2-Bromo-4-chloro-phenylamine (2.06 g, 10 mmol) and 4-tert-butylbenzenesulfonyl chloride (2.55 g, 11 mmol) were suspended in anhydrous pyridine (10 mL) and heated at 60° C. for 4 h. After cooling to room temperature the reaction mixture was added to 6 M HCl (100 mL) and the product was extracted with ethyl acetate (3×50 mL). The combined organic extract was dried over MgSO4, the solvent was evaporated, and the crude product was purified by flash chromatography to afford the title compound as a white solid. MS: (M+H)/z=403.
