実験手順
NBS (125.0 g, 697.5 mmol) was slowly added to a solution of TFA:H2SO4 (5:1, 750 mL) and tert-butyl-4-nitrobenzene (100.0 g, 558.0 mmol) at RT. The solution was stirred for 24 h then poured over 5 kg of ice. The resulting suspension was filtered and washed with a 1:1 MeOH:H2O solution (200 mL) and dried in a vacuum oven. MS (ES+): 258.1, 260.1 (M+H)+. Calc'd for C10H12BrNO2: 257.01.
