Hydrochloric Acid → 2-Aminomethyl-5,8-dimethyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one.HCl

Participants

Reaction Steps

2-Azidomethyl-5,8-dimethyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (2.76 g, 10.2 mmol) was dissolved in tetrahydrofuran (200 ml), to which 10% palladium-on-carbon (2.76 g) was added. The mixture was stirred at room temperature for 2 hours in the atmospher of hydrogen. The catalyst was filtered off, and the filtrate was condensed. The residue was converted to a hydrochloric acid salt, and then subjected to recrystallization (methanol-ether) to obtain 2.10 g of the title compound as yellow crystals (73.4%).
