Versuchsvorschrift

3-(1,2,3-triazol-1-yl)piperidine hydrochloride (63 mg, 0.33 mmol) and DBU (77 mg, 0.5 mmol) were added to a suspension of 5-methyl-1-cyclopropyl-6,7,8-trifluoro -1,4-dihydro-4-oxoquinoline-3-carboxylic acid (50 mg, 0.17 mmol) in acetonitrile (5 ml). The reaction mixture was refluxed under stirring for 66 hrs and then concentrated. The residue was diluted with water and thus separated solid was filtered, washed with water, acetonitrile and dried to give 35 mg of desired product. m.p. 227°-228.5° C.; 1H NMR (TFA) δ: 9.35 (s, 1H), 8.53 (s, 1H), 8.65 (s, 1H), 5.30 (m, 1H), 4.60 (m, 1H), 3.55-4.35 (m, 4H), 2.90 (s, 3H), 2.08-2.75 (m, 4H), 1.30-1.55 (m, 4H).
