الإجراء التجريبي

10% palladium/carbon (260 mg) was added to a THF (30 ml) and ethanol (15 ml) solution of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-ylmethyl 4-benzyloxybenzoate (2.6 g, 4.6 mmol). The mixture was subjected to hydrogen substitution and stirred at room temperature for 3 hours. After completion of the reaction, the catalyst was removed by conducting filtration using Celite, and the mixture was concentrated to dryness under reduced pressure, giving a pale yellow powder of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-ylmethyl 4-hydroxybenzoate (2.22 g, yield: quantitative).
