実験手順

To a suspension of 60 mg (0.2 mmol) of 5-amino -1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline -3-carboxylic acid and 80 mg of 3-(1,2,4-triazol-1-yl)pyrrolidine hydrochloride in 3 ml of dry pyridine under nitrogen was added 140 mg (0.9 mmol) of DBU, and the suspension was heated at 95° C. for 22 h. The resulting orange solution was then evaporated to dryness, water was added to the residue, and the orange solid was collected and washed with methanol to give 50 mg (60%) of yellowish solid after drying in vac-oven, m.p. 240.3°-242-3° C. 1H NMR (TFA) δ: 9.8 (s, 1H), 9.14 (s, 1H), 8.77 (s, 1H), 5.78-5.55 (m, 1H), 4.76-4.12 (m, 5H), 2.9-2.65 (m, 2H), 1.65-1.2 (m, 4H). Anal. calcd. for C19H18F 2 N6O3 : C, 54.81; H, 4.36; N, 20.17. Found: C, 54.52; H, 4.44; N, 20.00.
