실험 절차

Into a 100-mL round-bottom flask, was placed methyl 4-(1-(4-fluorophenyl)-2-methoxy-2-oxoethylamino)-3-nitrobenzoate (3.5 g, 9.67 mmol, 1.00 equiv), methanol (50 mL), and palladium on carbon (10%) (500 mg). Hydrogen gas was introduced to the reaction and it was stirred overnight at 30° C. in an oil bath. Then the solids were filtered off and the filtrate was concentrated in vacuo. This resulted in 2.6 g (90%) of methyl 2-(4-fluorophenyl)-3-oxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylate as a light yellow solid.
