[PROBLEMS] To provide a synthetic intermediate for a method for producing imidazolone and an imidazolidinone derivative having an antifungal activity, and a method for producing the same. SOLUTION: The formula: [Wherein, Ar represents a phenyl group which may be substituted; 1 represents a hydrogen atom or a lower alkyl group, R 2 represents an optionally substituted aliphatic be based have or aromatic hydrocarbon group or an optionally substituted aromatic heterocyclic group, R 3 Represents a group represented by the formula CH 2 Y (where Y represents a hydroxyl group or a halogen atom) or a formyl group which may be protected. Or a salt thereof, a method for producing the compound and a method for producing an imidazolone or an imidazolidinone derivative having an antifungal activity using the compound or a salt thereof. |
