Reaction Steps

2-(Methoxymethyl)-1-tosyl-1H-benzo[d]imidazol-5-amine. 2-(Methoxymethyl)-5-nitro-1-tosyl-1H-benzo[d]imidazole (0.9 g, 2.491 mmol) were dissolved in ethanol and purged with nitrogen. Palladium on activated carbon was added (0.530 g, 0.498 mmol), the nitrogen was evacuated and the reaction was stirred under 1 atmosphere of hydrogen for 16 h. The reaction mixture was filtrated through Celite and washed with ethanol. The organic layer was concentrated on a rotary evaporator to dryness to give desired product as purple solid, which was then crystallized from ethyl acetate in hexane to give the desired compound as a white solid (0.7 g, 85% yield). MS (ESI) m/z 332.2 [M+1]+.
