Procedure

A mixture of 7-fluoro-1-[2-(S)-fluoro-1-(R)-cyclopropyl]-5-hydroxy-8-methyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (205 mg, 0.694 mmol), 3-(R)-[1-(tert-butoxycarbonylamino)cyclopropyl]pyrrolidine (314 mg, 1.388 mmol), N-methyl piperidine (0.243 ml, 1.388 mmol), and dimethyl sulfoxide (1.5 ml) was stirred for 66 hours while heating in an oil bath at 80° C. under a nitrogen-replaced atmosphere. After evaporating the solvent, the residue was partitioned in chloroform (50 ml) and 10% aqueous citric acid solution (30 ml), and after separating the organic layer, the aqueous layer was further subject to extraction into chloroform (30 ml). The combined organic layer was then dried over anhydrous sodium sulfate, and after removing the drying agent by filtration, the solvent was evaporated under a reduced pressure to thereby obtain a crude 7-{3-(R)-[1-(tert-butoxycarbonylamino)cyclopropyl]pyrrolidin-1-yl}-1-[2-(S)-fluoro-1-(R)-cyclopropyl]-5-hydroxy-8-methyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acid.
