반응 단계
A mixture of 3.93 g of n-hexyl 3,4-dihydroxy-5-nitrophenylglyoxylate and 1.38 g of 2-aminophenol is melted at 120° while stirring. The melt crystallizes after 5 minutes. After 2 hours it is cooled and recrystallized from methanol. There is obtained 3-(3,4-dihydroxy-5-nitrophenyl)-2H-1,4-benzoxazin-2-one of m.p. 202°-204°.
