Versuchsvorschrift
To a solution of 1,1-dimethylethyl 4-nitro-1H-benzimidazole-1-carboxylate (0.95 g, 3.6 mmol) in ethanol (20 mL) was added 10% palladium carbon (0.10 g), and the mixture was stirred under hydrogen atmosphere at room temperature for 4 hours. The reaction solution was filtered through a Celite, the Celite was washed with ethanol, and then the filtrate was concentrated under reduced pressure to obtain the title compound (0.84 g, quantitative).
