FIELD: organic synthesis. SUBSTANCE: invention provides novel compounds of general formula C (see description), in which X denotes nitrogen atom, Y group -CH= or CR7 (wherein R7 is lower alkyl or halogen atom), Z group -CH=; R2a optionally substituted amino group or protected amino group, and R3 hydrogen atom or halogen. Pyridone- carboxylic acid derivatives and their salts showing antibacterial activity can be prepared from above-indicated amino compounds. EFFECT: expanded possibilities in synthesis of antibacterial agents. 5 cl, 2 tbl, 102 ex
