실험 절차

A mixture of 1-cyclopropyl-5,6,8-trifluoro-7-(3-methyl-1-piperazinyl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (150 mg) and 28% aqueous ammonia (15 ml) was heated at 100° C. for 48 hours in a sealed tube. The reaction mixture was evaporated to dryness under reduced pressure and water was added to the residue. The mixture was extracted with chloroform. After drying, the extract was evaporated and the residue was recrystallized from chloroform-ethanol to give 5-amino-1-cyclopropyl-6,8-difluoro-7-(3-methyl-1-piperazinyl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (93 mg), m.p. 251°-253° C.
