Reaction Steps

4-Bromo-2-fluoro-N,N-dimethylbenzenesulfonamide (1.0 g, 3.5 mmol) and sodium cyanide (350 mg, 7.1 mmol) were dissolved in DMF (3 mL) and irradiated in the microwave at 150° C. for 20 minutes. DMF was removed in vacuo and the residue was redissolved in dichloromethane (5 mL). The organics were washed with 5 mL of each 1N aqueous HCl, saturated aqueous NaHCO3, and brine. Organics were dried over Na2SO4 and evaporated to dryness. Crude product was purified by chromatography on silica gel (eluting with 0-50% ethyl acetate in hexanes) to afford 4-bromo-2-cyano-N,N-dimethylbenzenesulfonamide (72 mg, 7%). ESI-MS m/z calc. 288.0, found 288.9 (M+1)+; retention time 1.44 minutes.
