実験手順

1-Cyclopropyl-5-methyl-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (30 mg, 0.1 mmol) was reacted with 35 mg (0.2 mmol) of 3-(1,2,3-triazol-1-yl)pyrrolidine hydrochloride in 2 ml of dry pyridine under nitrogen in the presence of 30.4 mg (0.2 mmol) of DBU under reflux conditions. The solvent was removed under reduced pressure and to the orange viscous oil water was added and the solid was collected which was further purified from methanol to yield 20 mg of the desired product, m.p. 228°-230° C. 1H NMR (TFA) δ: 9.28 (s, 1H), 8.68 (s, 1H), 8.57 (d, 1.4Hz, 1H), 5.9-5.75 (m, 4.14 (m, 5H), 3.1-2.72 (m, 5H), 1.7-1.2 (m, 4H).
