실험 절차

Into a 100 mL 3-necked round bottom flask was placed a solution of ethyl 3-(2,4-dinitrophenyl)propanoate (1.5 g, 5.60 mmol) in methanol (20 mL). To the mixture was added Pd/C (0.5 g). Hydrogen gas was passed through. The resulting solution was allowed to react, with stirring, overnight while the temperature was maintained at 30° C. A filtration was performed. The filtrate was concentrated by evaporation under vacuum using a rotary evaporator. This resulted in 0.5 g (55%) of 7-amino-3,4-dihydroquinolin-2(1H)-one as a green-yellow solid.
