3-\x9b4-(4-Phenyl-1-butoxy)benzoyl!amino-2-hydroxyacetophenone is prepared by reacting a benzoate ester with a halobutylbenzene in the presence of a basic compound and an aprotic polar compound in an aromatic hydrocarbon solvent to obtain a corresponding ether, alkali hydrolyzing the ether in an aromatic hydrocarbon solvent and precipitating a hydrolysate with an acid to obtain 4-(4-phenyl-1-butoxy)benzoic acid, reacting a halogenating agent with this benzoic acid derivative in an aromatic hydrocarbon solvent to obtain an acid halide, and reacting the acid halide in an aromatic hydrocarbon solvent with a corresponding aromatic amine.
3-\x9b4-(4-苯基-1-丁氧基)苯甲酰胺-2-羟基乙酰苯酮是通过以下步骤制备的:在芳香族烃溶剂中,将苯甲酸酯与卤代丁基苯在碱性化合物和无极性极性化合物的存在下反应,得到相应的醚,然后在芳香族烃溶剂中进行碱水解,用酸沉淀水解物,得到4-(4-苯基-1-丁氧基)苯甲酸,再将卤代试剂与该苯甲酸衍生物在芳香族烃溶剂中反应,得到酸卤化物,最后将酸卤化物在芳香族烃溶剂中与相应的芳香族胺反应。
