| Zusammenfassung: | A process for producing an isoxazole derivative of general formula (II), wherein R and R may be the same or different from each other and each represents hydrogen or lower alkoxy, and R represents cyano or alkoxycarbonyl, by oxidizing an alpha , beta -unsaturated ketoxime derivative of general formula (I), wherein R , R and R are as defined above. The isoxazole derivative (II) is useful as an intermediate for the production of (3,4-diaryl-isoxazol-5-yl)acetic acid derivatives useful as an antiinflammatory, analgesic and antipyretic. |
