Hydrochloride methanol → HCID 67800902, compound

Participants

Reaction Steps

2-Azidomethyl-8-isopropyl-2,3,5-trimethyl-6,7-dihydrofuro[2,3-f]quinoline-7-one (1.25 g, 3.83 mmol) was dissolved in dimethylformamide (200 ml). To the solution, 10% palladium-on-carbon (1.45 g) was added, followed by stirring at room temperature for 90 minutes in the atmosphere of hydrogen. The reaction mixture was filtered, and the filtrate was condensed under reduced pressure. The resultant residue was suspended in methanol (50 ml), and the suspension was dissolved with 1.37 N HCl-methanol (4 ml, 5.31 mmol). The reaction mixture was condensed under reduced pressure, and the residue was recrystallized from methanol-ether to obtain 1.08 g of the title compound as colorless powdery crystals (83.7%).
