실험 절차

A solution of 135 mg (0.978 mmols) of potassium carbonate in 1 ml of water was added to a solution of 349 mg (0.978 mmols) of 2-(1-hydroxy-2-nonynyl)-3-methyl-4-acetoxy-6-fluoroquinoline, 20 ml of methanol and 2 ml of water and stirred at room temperature for 10 minutes. After neutralization with 1N hydrochloric acid, the solvent was distilled off under reduced pressure, followed by addition of 20 ml of chloroform to the resultant residue, washing with water and drying with sodium sulfate. The solvent was distilled off under reduced pressure, followed by purification by silica gel column chromatography (Wako gel C-200) (solvent: n-hexane : ethyl acetate=1:1) to obtain 183 mg (yield 59 %) of 2-(1-hydroxy-2-nonynyl)-3-methyl-6-fluoro-4-quinolone.
