実験手順
To a solution of 20.80 g (108.7 mmol) of N-acetyl-4-tert-butyl aniline and 0.33 g (2 mmol) of ferric chloride in 70 ml of acetic acid is added dropwise 17.9 g (112 mmol) of bromine while the temperature is kept between 30° C. and 40° C. Then the reaction mixture is stirred 4 hours and poured into 500 ml of ice water. The precipitate is filtered off, washed with water and recrystallized from 70% ethanol. Thus is obtained 24.33 g (83%) of title compound.
