Reaction Steps

To a solution of N-(4-aminobenzyl)-2,4-dinitroaniline (7) (21.6 g, 74.9 mmol) in anhydrous EtOH (300 mL) and anhydrous DMF (75 mL) was slowly added sodium methoxide (30% w/w) (69.1 g, 375 mmol) at room temperature under argon atmosphere, followed by heating to 60° C. for 2 hours. After cooling to ambient termperature, the solution was diluted with water (700 mL) and then acidified with saturated citric acid. The resulting precipitate was collected on a sintered funnel while rinsing with water. The crude product was recrystallized in hot EtOH to afford 18.1 g as a brown solid in 90% yield.
