Versuchsvorschrift

To a solution of 4-amino-N-tert-butyl-benzenesulfonamide (J. Med. Chem. (2003), 46(16), 3463-3475, 228 mg, 1.00 mmol) in DCM (10 mL), NBS (178 mg, 1.00 mmol) was added. The resulting mixture was stirred at RT for 30 min and washed with satd NaHCO3 (10 mL) and 10% aq Na2S2O3 (10 mL). The organic layer was separated, dried and concentrated to obtain 4-amino-3-bromo-N-tert-butyl-benzenesulfonamide (163 mg, 53%).
