Manufacturing Process

6,8-Difluoro-1-(2-fluoroethyl)-1,4-dihydro-7-(4-methyl-1-piperazinyl)-4- oxoquinoline-3-carboxylic acid hydrochloride:
A mixed solution of 1-methylpiperazine (0.34 g) and pyridine (3 ml) was added to 6,7,8-trifluoro-1-(2-fluoroethyl)-1,4-dihydro-4-oxoquinoline-3- carboxylic acid (0.12 g) and heated to reflux for 6 hours. After the solvent evaporated and cooled, the residue was adjusted to pH 1 with aqueous hydrochloric acid. The cooled mixture was filtered off and the solid recrystallized from water to give 6,8-difluoro-1-(2-fluoroethyl)-1,4-dihydro-7- (4-methyl-1-piperazinyl)-4-oxoquinoline-3-carboxylic acid hydrochloride (0.08 g), melting point 269-271°C (decomp.).
