실험 절차

To 1.57 g (5 mmol) of 5-amino-8-chloro-1-cyclo- propyl-6,7-difluoro-1,4-dihydro-4-oxo-3-quinoline carboxylic acid in 20 ml of acetonitrile was added 0.93 g (5 mmol) of 3-[(t-butoxycarbonyl)amino]pyrrolidine and 1.0 g (10 mmol) of triethylamine. The mixture was refluxed for three hours, cooled, and filtered. The solids were washed with acetonitrile and ether, then dissolved in 10 ml of acetic acid and 2 ml of 3 N hydrochloric acid. The mixture was heated at 100° C. for four hours, concentrated, and triturated with 2-propanol. The solid that formed was filtered and washed with ether to give 1.2 g of the title compound.
