실험 절차

A solution of 5-chloro-1,6-naphthyridine (500 mg, 3.04 mmol) in DMF (5 mL) was stirred at room temperature. Sodium azide (592 mg, 9.12 mmol) was added to the mixture, and the mixture was stirred at 80° C. for 4 h. The mixture was cooled to room temperature and filtered through Celite to remove a white solid. The filtrate was diluted with EtOAc (25 mL) and washed with brine (5×5 mL). The combined organic layers were dried with Na2SO4, filtered, and the solvent was removed under reduced pressure to yield 5-azido-1,6-naphthyridine as a yellow solid, which was used in the next step without further purification (500 mg, yield 96%). ESI MS: m/z 172 [M+H]+.
