Reaction Steps
A mixture of 4-nitrophthalic anhydride (10.0 g, 51.78 mmol) and IPA (180 mL) was stirred by a mechanical stirrer. Anhydrous hydrazine (2.77 mL, 56.96 mmol) was added dropwise and the reaction heated to 85° C. for 5 h. The reaction was cooled then acidified to pH 3 with conc. HCl. The solids were filtered and washed with IPA to afford the desired compound (7.76 g, 72%) as a pale yellow solid.
