Versuchsvorschrift

A mixture of 5-amino-1-(2,4-difluorophenyl) -6,7,8-trifluoro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid (200 mg, 0.54 mmol), 3-(1,2,3-triazol-1-yl)pyrrolidine hydrochloride (231 mg, 1.25 mmol) and diazabicycloundecane (200 mg, 1.31 mmol) in acetonitrile (25 ml) was refluxed for 45 h. The separated solid was filtered, washed with acetonitrile and ether to give 150 mg (57%) of desired product, m.p. 307.5°-309° C. 1H NMR (TFA) δ: 2.81 (m, 2H), 4.06-4.53 (m, 4H), 5.73 (m, 1H), 7.15-7.23 (m, 2H), 7.59-7.66 (m, 1H), 8.52 (d, 1H), 8.62 (d, 1H), 8.82 (d, 1H).
