Participants

Reaction Steps

A mixture of 2-(2-chloro-5-cyanophenylamino)-N-cyclohexylmethyl-1-methylbenzimidazole-5-carboxamide (500 mg, 1.19 mmol, prepared in analogy to the experimental procedures described above) and EtOH (20 mL) was saturated with ammonia. Freshly prepared Raney-Nickel (7 mg, 0.12 mmol) was added and the mixture was hydrogenated (rt, 70 atm) for 48 h. The mixture was filtered through Celite and the filter cake washed with EtOAc. The combined filtrates were concentrated and the residue treated with a mixture of petroleum ether and diethyl ether to give the sub-title compound. Yield: 500 mg (98%).
