실험 절차

To a 20 ml THF suspension of 1081 mg of (3-benzyloxypropyl)triphenylphosphonium bromide was added 258 mg of potassium, tert-butoxide followed by stirring for 1.5 hours. A 10 ml THF solution of 358 mg of 7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carbaldehyde was added thereto, followed by stirring for 1 hour. To the reaction mixture was added aqueous saturated ammonium chloride, followed by extraction with ethyl acetate and washing with aqueous saturated sodium chloride. After drying over anhydrous sodium sulfate and subsequent concentration under a reduced pressure, the residue was purified by silica gel column chromatography to obtain 488 mg of 3-[4-(benzyloxy)but-1-en-1-yl]-7-(cyclohexylamino)-1-(1-ethylpropyl)-6-fluoroquinolin-4(1H)-one.
