YieldReaction ConditionsOperation in experiment
82% A solution of 4-fluoro-Lambda/,Lambda/-dimethylbenzenesulfonamide (1.80 g; 8.86 mmol) in cone, sulfuric acid (7 ml; 130 mmol) was treated with Lambda/-bromosuccinimide (1 730 mg; 9.74 mmol) and stirred at RT for 3 h. The reaction mixture was carefully poured on crushed ice, extracted with AcOEt and the organic phase was washed with a 0.1 N solution of NaOH in water twice, then with brine twice. The organic phase was dried on MgSO4, filtered and concentrated under reduced pressure to give the title compound as a white solid (2.04 g, 82%).1H NMR (300MHz, DMSO-d6) delta [ppm] 8.04 (1 H, dd, J= 6.5 Hz, J= 2.2 Hz), 7.83 (1 H, ddd, J= 8.7 Hz, J= 4.6 Hz, J= 2.3 Hz), 7.66 (1 H, t, J= 8.7 Hz), 2.65 (6H, s).
