실험 절차
3-Nitro-7,8-dihydro-5H-[1,6]naphthyridine-6-carboxylic acid tert-butyl ester (1.0 g, 3.6 mmol), was added to EtOH (10 mL) in a sealed tube. 10% Pd/C (500 mg) was added and the mixture was heated to 170° C. for 16 h. The reaction mixture was cooled to RT, diluted with EtOH (10 mL), and filtered through Celite®. The solvent was removed under reduced pressure affording [1,6]naphthyridin-3-ylamine as yellow solid.
