Process for the preparation of N-arylaminoacrylic acid derivatives and the use of N-arylaminoacrylic acid derivatives thus prepared for the preparation of 4-quinolone-3-carboxylic acid derivatives |
摘要 |
N-arylaminoacrylic acid derivatives are obtained in good yields and in high purities when benzoylacetic acid derivatives are reacted with N-arylimino ethers. The products thus prepared are used, in particular, for the preparation of 4-quinolone-3-carboxylic acid derivatives, which have an outstanding bactericidal action.
