A mixture of 4-nitroisatoic anhydride (2.08 g, 10.0 mmol) and p-anisidine (1.35 g, 11.0 mmol) in N,N-dimethylformamide (10 mL) was heated at 80° C. for 2.5 h. After cooling, the reaction was poured into ice cold 3 N hydrochloric acid (60 mL). The resulting solid was filtered and washed with 1 N hydrochloric acid and water.
