Procedure
24.4 g. of α-[(2-Carboxy-6-methylphenyl)oxy]-γ-butyrolactone was added to 120 ml. of fuming nitric acid at a temperature not higher than -40° C. The reaction solution was poured into ice water, and the precipitating crystals were collected by filtration, washed with water and dried. The crystals were recrystallized from methanol. By the above procedure there was obtained α-[(2-carboxy-6-methyl-4-nitrophenyl)oxy]-γ-butyrolactone as pale yellow prisms, m.p. 210° C.(decomp.). Yield 20.3 g.
