Reaction Steps

step 1—To a solution of 4-bromo-3-fluoro-aniline (1.00 g, 5.263 mmol) in pyridine (5 mL) at 0° C. was added methanesulfonyl chloride (0.500 mL, 6.424 mmol). The reaction was gradually warmed to RT and stirred overnight then diluted with EtOAc. The organic layer was washed successively with saturated aqueous CuSO4 solution, brine, dried (Na2SO4), filtered and concentrated. The crude residue was purified by SiO2 chromatography eluting with an EtOAc/hexane gradient (5 to 20% EtOAc) to afford 1.235 g (88%) of N-(4-bromo-3-fluoro-phenyl)-methanesulfonamide (72) as a white solid.
