실험 절차

1-(4-Fluorophenyl)-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (0.33 g), 3,7-diazabicyclo[3.3.0] oct-1(5)-ene dihydrobromide (0.27 g) and 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU, 1 ml) were dissolved in acetonitrile (10 ml) and refluxed for 4 hours. The reaction mixture was kept overnight at room temperature and the produced precipitate was filtered, washed with acetonitrile, methanol to give the title compound (0.28 g, yield 66%).
