반응 단계
A mixture of 396.0 mg of n-hexyl 3,4-dihydroxy-5-nitrophenylglyoxylate and 137.6 mg of 1,2-phenylenediamine is heated to 120° for 60 minutes. Thereafter, the mixture is suspended in methanol, filtered under suction and recrystallized from N,N-dimethylformamide/water. There is obtained 3-(3,4-dihydroxy-5-nitrophenyl)-2(1H)-quinoxalinone of m.p. >300°.
