| titleOfInvention | Process for preparing pyridone carboxylic acid derivative |
| abstract | The present invention is prepared by oxidizing a compound of formula (XXV) or a salt thereof, wherein Z is cyano, to prepare a compound of formula (XXVI) or a salt thereof, and then performing a conventional Hoffman shift reaction, or Z is a formula (XXV). Reducing the compound of the present invention relates to a method for producing a compound of alban formula (I) or a salt thereof.n n n n n n n n n n n n n In which R 1 represents a hydrogen atom or a carboxyl protecting group; R 2 represents a hydrogen atom, a halogen atom, an alkoxy group, a protected or unprotected hydroxyl group, a protected or unprotected amino group, a protected or unprotected lower alkylamino group, or a di-lower alkylamino group; R 4 represents a hydrogen atom, a lower alkyl group, a halogeno-lower alkyl group, a protected or unprotected hydroxy-lower alkyl group or a lower alkylidene group, or together with a carbon atom to which R 4 is bonded a cycloalkane ring Form; X represents a halogen atom; A represents an oxygen or sulfur atom or a group of N-B, wherein B represents a hydrogen atom or a lower alkyl group; n represents an integer of 1 to 4; Z represents a cyano group or nitro group. The present invention also relates to novel intermediates for the preparation of compounds of general formula (I). |
