Procedure

To a 15 ml THF solution of 762 mg of 3-(3-{[tert-butyl(dimethyl)silyl]oxy}propoxy)-7-(cyclohexylamino)-1-cyclopentyl-6-fluoroquinoline-4(1H)-one was added 1.5 ml of a 1 M tetrabutylammonium fluoride THF solution at room temperature, followed by stirring for 2 hours. Water was added to the reaction mixture, followed by extraction with ethyl acetate and washing with aqueous saturated sodium chloride. After drying over anhydrous sodium sulfate, evaporation was carried out under a reduced pressure. By purifying the residue by silica gel column chromatography, 273 mg of 7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-3-(3-hydroxypropoxy)quinolin-4(1H)-one was obtained.
