Reaktionsschritte

3-Nitrophthalic anhydride was prepared from 3-nitrophthalic acid and acetic anhydride by the same procedure given for its 4-nitro isomer in Example 2. The yield of recrystallized product was 17.85 g (92.5%); m.p. 163°-164° C, whose percent elemental analysis of C, 49.79; H, 1.57; N, 7.22 is in excellent agreement with the theoretical values.
