3-Acetamido-4-nitrophthalic acid (0.538 g, 2.00 mmol) was dissolved in acetic anhydride (10 ml) at 80° C., and the solution was added with acetyl chloride (1 ml) and stirred for 2 hours. The solvent was evaporated, and a small amount of anhydrous dichloromethane was added to the residue, and precipitates were collected by filtration to obtain the title compound (0.29 g, 58%).
