Reaction Steps

A solution of 5-fluoro-1,3-diamino-2,4,6trinitrobenzene (1.57 g, 6 mmol) and urea (1.80 g, 30 mmol) in 30 ml of dry dimethylformamide (DMF) was heated for 1 hour at 90° C. A yellow precipitate formed after about 5 minutes. The mixture was cooled, poured into 150 ml of cold H2O and the solid filtered. Trituration of the solid with warm DMF-H2O (1:1, 100 ml), filtration and drying gave 5-ureido-1,3-diamino-2,4,6-trinitrobenzene (1.67 g, 92.3%): mp 350° C. dec; IR (KBr) 1730 cm-1 (C=O); mass spectrum (CI, CH4) m/z 259 (M+1-HNCO, 100).
