Reaction Steps

A 28% aqueous NH3 solution (2.0 ml) was added to a solution of 4-bromo-3-methyl-benzenesulfonyl chloride (250 mg, 0.927 mmol) in THF (2.0 ml) at 0° C. The mixture was stirred at 0° C. for 6.5 hours. The reaction mixture was quenched with 1 N HCl and extracted with CH2Cl2. The organic layer was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (CH2Cl2—AcOEt) to give 4-bromo-3-methyl-benzenesulfonamide as a white powder (126 mg, 54%).
