실험 절차

To a mixture of 20 g (0.1 mole) of 6-fluoro-5-nitroquinaldine in 180 ml of ethyl acetate and 20 ml of acetic anhydride were added 3 g of ten percent palladium on charcoal. The mixture was hydrogenated with hydrogen gas at 50 psi on a Paar apparatus for 20 minutes. The theoretical amount of hydrogen (25 psi) was used. On cooling, the mixture solidified to a yellow mass. About 200 ml of ethanol was added, and the mixture was heated to dissolve the product. The catalyst was filtered off through celite, and the filtrate was evaporated to dryness, leaving a yellow solid. This solid was triturated with 200 ml of water and neutralized with ten percent sodium hydroxide solution. Filtration and drying provided white crystals of 5-acetamido-6-fluoroquinaldine, m.p. 232°-235° C. The structural assignment was confirmed by infrared spectral analysis.
