実験手順

4-(1,2,3-triazol-1-yl)piperidine hydrochloride (126 mg, 0.66 mmol) and DBU (130 mg, 0.85 mmol) were added to a suspension of 1-cyclopropyl-5-methyl-6,7,8-trifluoro -1,4-dihydro-4-oxoquinoline-3-carboxylic acid (100 mg, 0.34 mmol) in acetonitrile (10 ml). The reaction mixture was refluxed for 24 hrs and then concentrated to dryness. The reaction was diluted with water. The separated solid was filtered and washed with water, acetonitrile and dried to give 70 mg of desired product. m.p. 261°-263° C.; 1H NMR (TFA) δ: 9.36 (s, 1H), 8.55 (s, 1H), 8.62 (s, 1H), 5.25 (m, 1H), 4.60 (m, 1H), 4.12 (m, 2H), 3.80 (m, 2H), 2.94 (s, 3H), 2.60 (m, 4H), 1.30-1.68 (m, 4H).
