Procedure

4 g (26.12 mmol) of 2,3-diaminonitrobenzene and 6.59 g (52.24 mmol) of commercial oxalic acid were dissolved in 50% acetic acid, and reaction was allowed at boiling point under an argon stream for 3 hr. After the reaction was over, the reaction mixture was cooled to room temperature, and the crystal precipitated was filtered out.
