By the use of 7-(2-chloromethylmorpholino)-1-ethyl-6,8-difluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid and dimethylamine, the reaction is similarly carried out as Example 34 to give 7-[2-(dimethylaminomethyl)morpholino]-1-ethyl-6,8-difluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid, melting at 185°-188° C.
