Reaction Steps

2-Amino-4-nitrobenzenethiol (315 mg, 1.85 mmol), 2-chlorobenzoic acid (290 mg, 1.85 mmol) and Eaton's reagent (5 mL) were combined and heated in the microwave at 130° C. for 10 min. After cooling, the mixture was poured into water and basified with 5M aqueous sodium hydroxide to give a precipitate, which was filtered off and dried to afford 530 mg (98%) of the title compound.
