Reaction Steps

4-Bromo-2-fluorobenzylamine (924 mg, 4.53 mmol) was dissolved in pyridine and ethane sulfonyl chloride (0.82 mL, 8.60 mmol) was added to the solution at 0° C. The mixture was stirred for 1 h at 0° C. Then, the mixture was quenched with 1N HCl and extracted with ethyl acetate (EtOAc). Drying (MgSO4) and evaporation of the ethyl acetate followed and the residue was purified by CC (eluent EtOAc/n-hexane) to yield N-(4-bromo-2-fluorobenzyl)ethanesulfonamide in pure form (1.06 g, 79%).
