Reaction Steps

To a solution of dimethyl 4-[2-(6-quinolinoxy)ethoxy]benzylidenemalonate (2.23 g, 5.47 mmol) in a mixture of methanol (20 ml) and 1,4-dioxane (150 ml) is added 5% palladium on charcoal (1.20 g). Then the mixture is stirred under an atmosphere of hydrogen at room temperature until hydrogen uptake ceased. The solution is filtered through Celite, and the filtrate is evaporated under a vacuum. The residue is crystallized from ethyl acetate to give the title compound (2.04 g, 90%). HRMS calcd for C23H27NO6: 413.4670. Found: 413.4672. MA calcd for C23H27NO6: C, 66.81%; H, 6.58%; N, 3.39%. Found: C, 66.53%; H, 6.55%; N, 3.36%.
