Versuchsvorschrift
To a mixture of 0.56 g of 3-amino-4-chloro-2-naphthoic acid and 20 ml of acetic acid was added dropwise 0.4 g of bromine at room temperature. The resulting mixture was stirred at room temperature for 1 hour. A deposited precipitate was collected by filtration, and the resulting solid was washed successively with acetic acid and ethyl acetate to obtain 0.36 g of 3-amino-7-bromo-4-chloro-2-naphthoic acid of the formula:
