Versuchsvorschrift

3-Amino-5-nitrobenzoic acid (910 mg, 5.0 mmol) was dissolved in EtOH (25 mL). DCC (1.51 g, 7.3 mmol) was added, and the mixture was stirred under reflux overnight. The solid precipitation was filtered off and the filtrate was evaporated. The residue was triturated in the solvent mixture ether:hexane:ethyl acetate, 5:5:1. The title compound was isolated as a fine light yellow powder (0.9 g, 85.7%).
