반응 단계
The progress of the bromination may be followed by thin layer chromatography or high pressure liquid chromatography so as to insure that the byproducts, 1-amino-2-bromoanthraquinone and 1-amino-4-bromoanthraquinone, represent less than 1% of the product mixture. This is essential, since hydroxylation of these two products results in 1-amino-2-hydroxyanthraquinone and 1-amino-4-hydroxyanthraquinone respectively. Both products are isolated along with the desired 1-amino-2-bromo-4-hydroxyanthraquinone and therefore give rise to a product with unsatisfactory quality.
