Reaction Steps

28 g N-3-(imidazol-1-yl)propyl-3-nitroaniline was dissolved in 450 ml ethanol and 50 ml water, and 0.3 Pd/C (5%) was added. After purging with nitrogen, hydrogenation was performed for 12 h at 50° C. under 50 bar of hydrogen pressure. After cooling, nitrogen purging was repeated, the catalyst was filtered off, and the filtrate was reduced on a rotary evaporator. 18.2 g of black oil was obtained; this was distilled in a ball tube (265–387° C., 0.06–0.08 mbar). The product obtained was an amorphous orange solid.
