NOVEL PYRIDONE CARBOXYLIC ACID DERIVATIVES AND THEIR PREPARING METHOD

摘要

Pyridone carboxyl acid derivative of general formula(I) is obtained by reacting a compound of general formula(II) with Z-N new compound and separating the product. Here, R1 is low-level alkyl group, halogen-substituted low-level alkyl group, low-level alkenyl group, cycloalkyl group or is substituted or non-substituted phenyl group. R2 is hydrogen, low-level alkyl group or amino group. A is nitrogen atom or C-X(here X is hydrogen, halogen atom or alkoxy group) and Z means group indicated as the general formula(I). In the general formula(II), Y is halogen atom and R7 is hydrogen or low-level alkyl group.
