참여 물질

반응 단계

2-Azidomethyl-5-methyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (759 mg) was dissolved in dimethylformamide (20 ml). To the solution, 10% palladium-on-carbon (455 mg) was added, and the solution was hydrogenated in the atmosphere of hydrogen at ambient temperature and under atmospheric pressure. After completion of the reaction, the catalyst was filtered off. When the solvent was evaporated, 0.7 g of the title compound was obtained as a crude product. This product was purified by silica gel column chromatography to obtain 409 mg of a free base (60.0%). The obtained free base was converted into a hydrochloric acid salt, followed by recrystallizing from a solvent mixture of methanol-diethylether, obtaining yellow powdery crystals having a melting point over 300° C.
