実験手順

A mixture of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.5 g), anhydrous acetonitrile (5 ml), 3-ethylaminomethyl-4-methylpyrrolidine (0.38 g) and DBU (0.27 g) was refluxed for an hour and allowed to stand overnight at room temperature. The resulting precipitate was collected by filtration, washed with acetonitrile and ether successively and recrystallized from chloroform-methanol-concentrated aqueous ammonia to give the title compound (0.47 g) as pale yellow powder, mp 224°-226° C.
