反応手順
A solution of N-(2-nitrophenyl)glycine methyl ester (740 mg, 3.6 mmol) in ethyl acetate (50 ml) and methanol (25 ml) was hydrogenated at atmospheric pressure over a catalytic amount of 10% palladium on carbon. After 1 h the mixture was filtered and reduced to afford 1,2,3,4-tetrahydroquinoxalin-2-one as a yellow solid (530 mg, 99%).
