Reaction Steps
Example 1 was repeated except that 59.2 g (200 mmoles) of the 2,4-dibromo-6-nitroaniline and 21.6 g (200 mmoles) of p-methylphenol were used instead of 36.4 g (200 mmoles) of 4-amino-3-nitrobenzoic acid and 27.6 g (200 mmoles) of p-hydroxybenzoic acid respectively to obtain 4,6-dibromo-2-(2'-hydroxy-5'-methylphenyl)benzotriazol. The yield was 60%.
