Reaktionsschritte

(RS)-8-[3-(4-Cyanophenyl)-1-piperazinyl]-7-fluoro-1-methyl-4-oxo-1,4-dihydrobenzo[b][1,8]-naphthyridine-3-carboxylic acid was prepared under the conditions of Example 11, but starting with 8-chloro-7-fluoro-1-methyl-4-oxo-1,4-dihydrobenzo[b][1,8]-naphthyridine-3-carboxylic acid (1.84 g), (RS)-2-(4-cyanophenyl)piperazine (5.61 g) and triethylamine (1.7 cc). (RS)-8-[3-(4-Cyanophenyl)-1-piperazinyl]-7-fluoro-1-methyl-4-oxo-1,4-dihydrobenzo[b][1,8]-naphthyridine-3-carboxylic acid (1.15 g) is obtained in the form of a yellow solid, decomposing at 332° C.
