3-Nitro-benzene-1,2-diamine (1.0 g, 6.54 mmol) and butyraldehyde (630 μL, 7.19 mmol) were stirred in POCl3 (10 mL) at 85° C. for 3 hours. The reaction was cooled to ambient temperature and poured over ice. The resulting mixture was basified with NH4OH. The precipitate was filtered and washed with ice water to give 1.17 g of the sub-title compound that was used without further purification.
