実験手順
A mixture of N′-(6-cyano-3-methyl-2,4-dinitro-phenyl)-N,N-dimethyl-methanimidamide (8) (0.607 g, 2.42 mmol) and 10% palladium on carbon (0.23 g of 50% water wet) and methanol (60 mL) is agitated under hydrogen pressure (43 psi) for about 4.5 hours. The vessel is then flushed with nitrogen and the mixture is heated to 60° C. for about 2.5 hours. The mixture is allowed to cool to ambient temperature and is then filtered through a pad of Celite. The solvent is then evaporated in vacuo to provide 6-Amino-7-methyl-1H-benzimidazole-4-carbonitrile (10) (0.426 g, >100% crude Yield), as a brown solid.
