There is disclosed a method of manufacturing a 3-substituted-3-oxo-2-halopropionic acid amide compound, comprising halogenating a 3-substituted-3-oxopropionic acid amide compound with a 1,3-dihalo-5,5-dimethylhydantoin. There is also disclosed a method of manufacturing a 3-substituted-3-oxo-2-(5,5-dimethylhydantoin-3-yl)propionic acid amide compound, comprising steps of halogenating a 3-substituted-3-oxopropionic acid amide compound with a 1,3-dihalo-5,5-dimethylhydantoin, to obtain a corresponding 3-substituted-3-oxo-2-halopropionic acid amid compound, and reacting the resultant amide compound with 5,5-dimethylhydantoin in the presence of a base. This 3-substituted-3-oxo-2-hydantoinylpropionic acid amide compound is useful as a photographic yellow coupler for a color-photographic light-sensitive material.
本发明公开了一种制造3-取代-3-氧代-2-卤代丙酸酰胺化合物的方法,包括使用1,3-二卤-5,5-二甲基咪唑烷酮对3-取代-3-氧代丙酸酰胺化合物进行卤代反应。本发明还公开了一种制造3-取代-3-氧代-2-(5,5-二甲基咪唑烷酮-3-基)丙酸酰胺化合物的方法,包括以下步骤:使用1,3-二卤-5,5-二甲基咪唑烷酮对3-取代-3-氧代丙酸酰胺化合物进行卤代反应,得到相应的3-取代-3-氧代-2-卤代丙酸酰胺化合物,并在碱的存在下将所得的酰胺化合物与5,5-二甲基咪唑烷酮反应。这种3-取代-3-氧代-2-咪唑烷基丙酸酰胺化合物可用作彩色照相感光材料的黄色偶合剂。
