실험 절차

1.15 g (3.5 mmoles) of 1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinolinecarboxylic acid are stirred in 20 ml of dimethylformamide with 0.85 g (4.4 mmoles) of 4-bromomethyl-5-methyl-1,3-dioxol-2-one and 0.42 g (4.2 mmoles) of powdered potassium bicarbonate for 3 days, while cooling with ice. The mixture is concentrated in vacuo, the residue is stirred with 20 ml of water, the resulting greasy product is dissolved in methanol and the solution is filtered. The filtrate is left to stand at room temperature for 2 days and the colorless crystals which have precipitated are isolated.
