Reaction Steps

2-(5-Nitrobenzimidazolyl)amino-2-imidazoline (12.80 g,) was dissolved in anhydrous dimethylformamide (200 ml) and hydrogenated at 50 psi and room temperature for 48 hours, over 5% palladium charcoal (500mgs). The filtered reaction mixture was evaporated under reduced pressure to yield 2-(5-aminobenzimidazolyl)amino-2-imidazoline (9.87g), characterised as the dihydrochloride (7.60g) (m.p. 285°C).
