Reaction Steps
2.20 g. (9.2 mMole) 5,6-dinitro-1-methylbenzimidazol-2-one is hydrogenated for 3 hours at 60° C. and 100 bar hydrogen pressure in 730 ml. methanol in the presence of 0.44 g. platinum oxide. The solution of 5,6-diamino-1-methyl-benzimidazol-2-one so obtained is, after filtration, used without further purification.
