실험 절차

Over a 30 minute period and with constant stirring, add 16 g. of bromine dissolved in 50 ml. of glacial acetic acid to a mixture of 37 g. of N-(2-methyl-3-trifluoromethylphenyl) anthranilic acid in 350 ml. of glacial acetic acid. Pour the resulting mixture into 1500 ml. of water, filter and dry the precipitate. Recrystallize the product from acetonitrile to obtain 5-bromo-N-(2-methyl-3-trifluoromethylphenyl) anthranilic acid, m.p. 223°-225° C.
