반응 단계
A solution of 1.07 g of n-hexyl 3,4-dihydroxy-5-nitrophenylglyoxylate and 696.3 mg of 2,3-diaminonaphthalene in 3 ml of 1-hexanol is heated to boiling under reflux for 3 hours. The reaction mixture is then cooled and diluted with methanol. The crude product is filtered under suction and recrystallized from N,N-dimethylformamide/water. There is obtained 3-(3,4-dihydroxy-5-nitrophenyl)benzo[g]quinoxalin-2(1H)-one of m.p. >300°.
