Procedure
Ethyl 6-fluoro-1,4-dihydro-4-oxo-7-(4-trifluoroacetyl-1-piperazinyl)-1,8-naphthyridine-3-carboxylate was treated with ethyl iodide and potassium carbonate in dimethyl formamide by the same procedure as described in Example 1 to form ethyl 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(4-trifluoroacetyl-1-piperazinyl)-1,8-naphthyridine-3-carboxylate. This product was hydrolyzed by treating with aqueous potassium carbonate in a mixture of chloroform and methanol to give ethyl 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-1,8-naphthyridine-3-carboxylate, m.p. 150°-151° C.
