More Information
Summary: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 photogrpahi yellow coupler for a color-photographic light-sensitive material.
