Reaction Steps

3-Nitro-benzylamine (2.3 g, 15.1 mmol) was dissolved in anhydrous dioxane (50 ml) under N2 atmosphere. Diphosgene (2.2 ml, 18.2 mmol) was added, a precipitate formed which dissolved upon heating to 75° C. The reaction was stirred at 75° C. for 3 h, cooled and evaporated to dryness giving 3.4 g of crude material which was used in the next step without further purification.
