three-step procedure has been developed for synthesis of substituted 2-aminobenzophenones from substituted anilines. The anilines are first protected as acetanilides, by reaction with acetic anhydride. These are then benzoylated with (trichloromethyl)benzene in the presence of aluminium-generated 2-acetamidobenzophenone. Finally, removal of the acetyl group from the amino group provides the substituted 2-aminobenzophenones
已经开发了一种方便的三步程序,用于从取代的苯胺合成取代的2-氨基二苯甲酮。首先通过与乙酸酐反应将苯胺保护为乙酰苯胺。然后在铝生成的2-乙酰氨基二苯甲酮存在下,将它们与(三氯甲基)苯苯甲酰化。最后,从氨基上除去乙酰基以中等到良好的产率提供了取代的2-氨基二苯甲酮。
