Reaction Steps

A mixture of 2.0 g (7.3 mmol) N-benzyl-2,4-dinitroaniline, 1.50 g (28.0 mmol) ammonium chloride, 6.7 g (28.0 mmol) sodium sulfide hydrate and 100 ml methanol was refluxed for 3/4 h. After cooling to 25° C. the mixture was filtered and evaporated. The product was stirred with water to give 1.3 g (73%) N-benzyl-2-amino-4-nitroaniline. 1H-NMR (CDCl3): 8.1-6.5 (8H, m), 4.9-4.3 (3H, m), 3.4 (2H, broad s).
