Reaction Steps

To a solution of 3-benzoxazol-2-yl-5-bromo-phenylamine (0.12 g, 0.42 mmol) in pyridine (2.0 mL) at room temperature was added methanesulfonyl chloride (0.14 g, 1.30 mmol) and catalytic DMAP. The resulting mixture was stirred at room temperature for 17 hours. The solvent was removed under vacuum and the residue was purified by preparative TLC eluting with 4:1/hexanes:ethyl acetate to give N-(3-benzoxazol-2-yl-5-bromo-phenyl)-methanesulfonamide (85.0 mg, 55%) as a yellow solid.
