実験手順

A mixture of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.6 g), anhydrous acetonitrile (5 ml), 3-aminomethyl-4-methylpyrrolidine (0.29 g) and DBU (0.33 g) was refluxed for an hour and then stirred at room temperature for 2 hours and allowed to stand overnight. The resulting precipitate was collected by filtration and recrystallized from chloroform-methanol-concentrated aqueous ammonia (10:10:1) to give the title compound (0.45 g) as colorless prisms, mp 249°-252.5° C.
