실험 절차

1-Cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (150 mg, 0.53 mmol) was reacted with 249 mg (1.33 mmol) of 3-(4-methyl-1,2,3-triazol-1-yl)pyrrolidine hydrochloride in the presence of 201 mg (1.33 mmol) of DBU in 15 ml of dry pyridine under nitrogen at 120° C. for 3 days. Small amounts of the solid present were removed by filtration, and the supernatant was concentrated under reduced pressure. Water and small amounts of acetonitrile were added to the residue and the grey solid was collected and dried to afford 180 mg (82%) of the desired product, m.p. 219°-220° C. 1H NMR (CDCl3) δ: 8.73 (s, 1H), 7.85 (dd, J=13.7Hz, 1.9HZ, 1H), 7.42 (s, 1H), 5.4-5.3 (m, 1H), 4.4-3.7 (m, 5H), 2.7-2.5 (m, 2H), 2.37 (s, 3H), 1.4-1.05 (m, 4H). Anal. calcd. for C20H19F2N5O3 : C, 57.83; H, 4.57; N, 16.86. Found: C, 57.81; H, 4.60; N, 16.31.
