실험 절차

A solution of 1,2-dihydro-2,2-dimethyl-6-nitro-3-(4H)-quinoxalinone (663 mg, 3 mmol) in CH3OH (10 ml) is hydrogenated with 50 psi H2 (g) at room temperature in the presence of a catalyst of 10% by weight palladium on charcoal (50 mg). After the starting material is consumed, the solution is filtered and concentrated in vacuo to yield 6-amino-1,2-dihydro-2,2-dimethyl-3-(4H)-quinoxalinone.
